> I then decided to contact Insulet to get the kernel source code for it, being GPLv2 licensed, they're obligated to provide it.
This is technically not true. It is an oversimplification of the common case, but what actually normally should happen is that:
1. The GPL requires the company to send the user a written offer of source code.
2. The user uses this offer to request the source code from the company.
3. If the user does not receive the source code, the user can sue the company for not honoring its promises, i.e. the offer of source code. This is not a GPL violation; it is a straight contract violation; the contract in this case being the explicit offer of source code, and not the GPL.
Note that all this is completely off the rails if the user does not receive a written offer of source code in the first place. In this case, the user has no right to source code, since the user did not receive an offer for source code.
However, the copyright holders can immediately sue the company for violating the GPL, since the company did not send a written offer of source code to the user. It does not matter if the company does or does not send the source code to the user; the fact that the company did not send a written offer to the user in the first place is by itself a GPL violation.
This is an open legal question, which the Conservancy v Vizio case will hopefully change; in that case, Conservancy is arguing that consumers have the right to enforce the GPL in order to receive source code.
Linus rants that the SFC is wrong and argues that the GPLv2 which the kernel is licensed under does NOT force you to open your hardware. The spirit of the GPLv2 was about contributing software improvements back to the community.
Which brings us to the question: what is this guy going to do with (presumably) the kernel source? Force the Chinese to contribute back their improvements to the kernel? Of which there are likely none. Try and run custom software on his medical device which can likely kill him? More than likely.
The judge's comments on the Vizio case are such that should this guy get his hands on the code, he has no right to modify/reinstall it AND expect it will continue to operate as an insulin pump.
This is about as ridiculous as buying a ticket on an airplane and thinking you are entitled to the source code of the Linux in-seat entertainment system.
There are a lot of people hacking on insulin pumps and they are lightyears ahead of commerce. If you want a very interesting rabbit hole to dive into try 'artificial pancreas hacking' as google feed.
I would trust the people that hack on these systems to be even more motivated than the manufacturers to make sure they don't fuck up, it's the equivalent of flying a plane you built yourself.
> it's the equivalent of flying a plane you built yourself
A great analogy because people die that way. I personally would never push code to another person’s insulin pump (or advertise code as being used for an insulin pump) because I couldn’t live with the guilt if my bug got someone else killed.
I know people die that way (GA). But someone is working for the companies that make insulin pumps and they are not as a rule equally motivated so I would expect them to do worse, not better.
And to the best of my knowledge none of the closed-loop people have died as a result of their work and they are very good at peer reviewing each others work to make sure it stays that way. And I'd trust my life to open source in such a setting long before I'd do it to closed source. At least I'd have a chance to see what the quality of the code is, which in the embedded space ranges from 'wow' all the way to 'no way they did that'.
Anytime anybody does something himself, there is a risk. People die because of welding parts cleaned with break-cleaner, people die driving, diving, sky-diving, doing bungee jumping...
Advertising that code, IMHO would be as showing of you doing extreme sports, for example. I do not think is any bad. A good disclaimer should be enough to take away any guilt.
I'm not aware of any deaths attributed to open source artificial pancreas systems. Meanwhile there have been multiple attributed to closed source glucose monitors.
And yet someone IS pushing code to these devices. Every single one.
So the question really becomes - Are these people working on their own pumps with open source more or less invested than the random programmers hired by a company that pretty clearly can't get details right around licensing, and is operating with a profit motive?
More reckless as well? Perhaps. But at least motivated by the correct incentives.
> I would trust the people that hack on these systems to be even more motivated than the manufacturers to make sure they don't fuck up
I would think it's the opposite. People that hack on this only risk their own life. Companies risk many people's lives and will get sued. Of course the person doing the hacking doesn't want to die but they're also willing to take the risk.
The absolute worst-case scenario of messing this up as a company is that you get sued and they win, or you're forced to settle. You pay out some money, post a public apology, whatever. If things get really bad, the company goes under. But you're likely still far richer than the average person, and the blame is distributed enough that no one gets a criminal sentence - not that it was a realistic option to begin with.
The baseline worst-case scenario of messing this up on yourself is that you die.
Right, but getting sued is basically the least risky activity ever. Okay, a little dramatic but: you won't go to jail, and if you're rich and become less rich you're still better off than most people. In pure absolutionist terms, being a business owner is basically always less risky than being labor.
A lot of the other responses say something along the lines of "of course people have more incentive not to mess up, they care about their own lives more than corporations care about getting sued" and sure, that's true in general, but:
- people try to wingsuit through narrow obstacles and miss
- people try to build their own planes and helicopters and die
- people try to build submersible vehicles to go see the titanic and, uh, don't have a 100% success rate
- people try to build steam-powered rockets and die
"It's their life, they won't fuck it up" doesn't exactly cover a lot of behaviors.
I'd argue home-rolling your own medical device firmware is closer to daredevil/"hold my beer" behavior than normal.
> The spirit of the GPLv2 was about contributing software improvements back to the community.
It may be the case that when all is settled, the courts determine that the letter of the license means others' obligations are limited to what the judge in the Vizio case wrote. And Linus can speak authoritatively about his intent when he agreed to license kernel under GPL.
But I think that it's pretty clear—including and especially the very wordy Preamble—not to mention the motivating circumstances that led to the establishment of GNU and the FSF, the type of advocacy they engage in that led up to the drafting/publication of the license, and everything since, that the spirit of the GPL is very much in line with exactly the sort of activism the SFC has undertaken against vendors restricting the owners of their devices from using them how they want.
Why is it ridiculous? If the license says you have the right to obtain the source code to software that was distributed to you, then you have the right to obtain the source code. It doesn't matter what your intended use of it is.
Rather crucially, the license itself does not say that you have the right to the source code. It is only the separate written offer which gives you that right. If you did not receive such an offer, you don’t have any right to it. But then, the company has already, unquestionably, violated the GPL, and the company can be sued immediately. Specifically, you don’t have to first ask the company for the source code! The lack of a written offer is in itself a clear violation.
> But then, the company has already, unquestionably, violated the GPL, and the company can be sued immediately.
You were right up to this point. Medical devices requiring a prescription must be obtained via specialized suppliers, like a pharmacy for hardware. These appliances are not sold directly to end users because they can be dangerous if misused. This includes even CPAP machines.
In theory, that written offer only needs to go to the device suppliers. Who almost universally have no interest in source code. When the device is transferred or resold to you, it need not be accompanied by the offer of source.
If that was true, anyone reselling an Android phone could open themselves up to legal liability. Imagine your average eBayer forgetting to include an Open Source Software Notice along with some fingerprint-encrusted phone.
You already created an interesting top-level comment analyzing the difference between "offering" and "providing" which has a lot of discussion. I'm just saying it's not "ridiculous" to expect software licensing terms to be applied and enforced, whatever a judge decides those terms end up meaning.
It's a medical device that requires a prescription. You can't buy it off the shelf. They're not distributing software to you either. You must go through a medical equipment supplier who transfers the device to you after insurance has paid for some or all of it.
For the same reason you can't find an airplane entertainment system in the trash and call up the company and demand source code.
It doesn't matter what form it takes. Compiled binaries of GPL code are being distributed. The recipients of that binary are entitled to the source of the GPL portions in a usable form:
"The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable."
The GPL here doesn't extend beyond the kernel boundary. Userland is isolated unless they have GPL code linked in there as well. If they were careless about the linkage boundaries then that's on them.
> This is about as ridiculous as buying a ticket on an airplane and thinking you are entitled to the source code of the Linux in-seat entertainment system.
If you have a pacemaker implanted, do you believe you have the right to modify and update the software that operates it? Separately, do you think it's remotely a good idea?
> If you have a pacemaker implanted, do you believe you have the right to modify and update the software that operates it?
Yes, of course. It is abhorrent that people have devices implanted into their bodies and are in any way prevented from obtaining every last detail about how those devices operate.
> Separately, do you think it's remotely a good idea?
In rare circumstances, yes. See, by way of example, Karen Sandler's talk on her implanted pacemaker and its bugs, for specific details on why one might want to do so.
Obviously yes to the first question. How could you possibly not have the right to operating your own heart.
Naturally it would generally not be a good idea.
>Which brings us to the question: what is this guy going to do with (presumably) the kernel source?
it doesn't bring us to the question, but the answer to the question is, run a diff between the software that has this guys life in its hands, and the version it was derived from, to see if they inserted back doors, stray pointers, etc.
>> Try and run custom software on his medical device which can likely kill him? More than likely
I think this sentence is very sad. Not only this is a hard accusation, it is also the primary argument of the anti right to repair movement. An argument that I think is extremely bogus and ill intentioned, and I particularly (like Mr. Rossman) viscerally dislike.
Maybe the primary motivation is a) curiosity, and b) just for kicks to know if they honor the license.
If you carefully read what I wrote, you will notice that I never claimed otherwise. Whether or not third parties have standing to sue on a GPL violation is immaterial to my point, none of which is “an open question”.
> The GPL requires the company to send the user a written offer of source code
It should be noted that this is just one of three options that someone who wants to distribute binaries of GPL code can choose from. It's the most commonly chosen one, and one is only available for noncommercial distribution, so the odds are good that this is the option they are using.
The other available option is to accompany the binary with the source code.
That one leads to an interesting possibility where someone could end up with a binary and there is no one obligated to provide source to them. As far as I know this has not actually arisen, but it seems like something that is bound to happen sometime.
Suppose company X decides to make a generic hardware platform that other companies can buy to build their products on. X's platform is basically a small single board computer with WiFi, Bluetooth, dual, USB ports, a couple Ethernet ports, and some GPIO ports. X ports Linux to their hardware.
When X ships a system it comes with an SD card with a Linux distribution installed including their custom kernel. It is configured to boot from the first SD card slot, and then to run a custom login system that looks at the second SD card slot and if there is a card in there it mounts it, looks for an executable on its root name application.exe, and runs that as root. X includes in the box a small thumb drive with a copy of the source code for everything on the SD card.
The idea is that a company Y that wants to make something like a WiFi access point or an air quality monitor can buy these boards from X, put them in a case with whatever peripherals or sensors they need like air quality sensors, write the software for the application, put it on an SD card, and put that in the second SD card slot.
So lets say Y buys 1000 of these systems from X, builds 1000 of their access points or whatever from them, and sells them.
One of their customers asks Y for the source code of the GPL parts. Does Y have to provide it?
I'd say they do not. They are not making copies or derivative works. They are just receiving physical copies from X and passing those on unmodified to their customers. This should fall squarely under the First Sale Doctrine in US copyright law, and similar rules in other jurisdictions.
How about if they ask X for a copy?
X has made copies and derivative works and distributed them. But X satisfied their GPL requirements by including a thumb drive with the source with each board they shipped to Y.
The written offer is part of the licence, as is the need to respond to that offer with the source code offered. It is all part of the same agreement.
A written offer on its own would not normally be directly enforceable in many (most?) jurisdictions, for the same sort of reason that retailers can't be held to incorrectly published prices (in the UK at least, a displayed price is an “invitation to tender”, not a contract or other promise) except where other laws/regulations (anti bait&switch rules for instance), or the desire to avoid fighting in the court of public opinion, come into effect.
But in this instance, the written offer and the response to that offer are part of the wider licence that has been agreed to.
> If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code.
That section (and similar in section 6d) is not about the written offer of source code. The written offer of source code is instead covered in section 6c.
> the same sort of reason that retailers can't be held to incorrectly published prices (in the UK at least, a displayed price is an “invitation to tender”, not a contract or other promise)
The hell? Over here, the price tags are a sort of public contract, to which the seller pre-commits. The seller forgot to change the tags? That's not the buyer's problem.
Since money has not exchanged hands, you could always decide not to buy at the counter. So atleast in the countries I have been, it is not legally binding.
Offer and acceptance are part of how contracts are formed. There is no contract without there first being an offer.
If you accept someones offer, provided it meets the rest of the criteria for a valid contract - congratulations you now have a contract. If the any party violates it, yes this is a breach of contract.
> A written offer is not the same thing as a contract.
An offer is a precondition and component of a contract
The customer spends money to buy the product along with the source code offered. It's part of the transaction. Not honoring part of the transaction is a breach of contract.
I think they're just saying the GPL doesn't really cover consumer/distributor (dis)agreements, it only covers copyright. While the spirit of the GPL is user-first, it still has to be realized within the confines of copyright law. Even though many people might conflate the spiritual goal and the legal agreement, it doesn't grant "users" any extraordinary legal powers.
It's not illegal to not honor written offers, it's illegal to distribute copyrighted material in violation of it's license.
So gpl is a licensor-licensee contract, if code and license is not shared to the user, then there is no contract to which the user is a party, rather the user is a beneficiary.
The offer of source code seems to be a way to facilitate the conveyance of source code through opt-in means separately from the object code rather than some legal trickery to create a user-licensee contract.
While the offer may indeed convey a licensee-user obligation, a compliant distribution would attach a license anyway, converting the user into a licensee and licensor to licensee in a recursive fashion
I wonder if lawyers specialize in this, it sounds very cool and not at all standard law, but somehow compatible with contract law
On the shelves are three insulin pumps: one with a 5-year warranty, one at a bargain barrel price that comes with no warranty, and one accompanied by a written offer allowing you to obtain the source code (and, subject to the terms of the GPL, prepare your own derivative works) at no additional charge any time within the next three years.
Weighing your options, you go with pump #3. You write to the company asking for the GPL source. They say "nix". They're in breach.
The GPLv2 under which Linux is licensed does not prohibit that insulin pump from bricking itself if you tried to install "your own derivative work" that wasn't signed by the manufacturer.
This is not only possible but also prudent for a device which can also kill you.
Maybe it’s not technically “breach of contract”, and an offer might or might not be a contract. But if you don’t honor an offer you made, you must surely be guilty of something. Otherwise, all offers would be meaningless and worth nothing.
> you must surely be guilty of something. Otherwise, all offers would be meaningless and worth nothing.
You don't have to be "guilty" of anything to be liable in civil law (which contract law is a part of). "Guilt" is a concept from criminal law. It isn't required for contracts to be enforceable.
In general (there are exceptions) offers alone aren't enforceable and don't result in a contract. You need other elements (agreement by the parties, plus something done in return for what's offered) for a contract to be formed - and then it's enforceable.
The written offer with a limited term of three years is just one permitted method of distribution. If an offer was never made then they're not covered by that clause and are bound to comply by other means without the protection of the three year window.
Yes. I did not cover these cases because approximately nobody does that.
I mean, the absolutely simplest, and cheapest, way for companies to comply with the GPL is to ship the source code together with the software. Stick it in a zip file in a directory somewhere. The company can then forget the whole thing and not worry about anyone contacting them and ranting about source code and the GPL. But no company does that.
The other simple way for companies to comply with the GPL is for companies to provide a link to download the source code at the same place that users download the program itself. If the user did not download the source code when they had the chance, that’s the user’s problem. This will also let the company ignore any GPL worries. No company does this, either.
(The GPL provides a third way for individuals and non-profits, which is not relevant here.)
What's the consideration in the written offer? Promises aren't enforceable in court. For a contract to be enforceable, it has to be an exchange of something, not a one sided offer.
Maybe. Who can and cannot sue is irrelevant to my point. But I seriously doubt that anyone can sue for source code. Someone might sue for damages, and the company might offer to settle by offering source code. But IIUC, no company can be sued and forced to give up any source code, unless the company itself chooses to do this instead of paying damages.
I don't know how easy it is in Germany compared to the U S., but this is false. In the U.S., you absolute can sue (and it is extremely common) to force certain actions. See: constructive trust, mandatory injunction, prohibitive injunction, specific performance, recission, writ.
In all likelihood, you would not receive the source code in the U.S., though. If deadset against release, the outcome would likely be that the offender would be fined and injoined from any further distribution.
Not according to the original reasoning by its creators, but opinions differ wildly. However, this is irrelevant to the point; the written offer, which is separate from the GPL, is what is failing to be honored, not the GPL. If you did not receive such a written offer, the GPL, in itself, makes no guarantee that you have the right to the source code.
> If you did not receive such a written offer, the GPL, in itself, makes no guarantee that you have the right to the source code
Wrong. The requirement to provide source code under the GPL is primarily governed by Section 3 of the GNU General Public License v2 and Section 1 of the GNU General Public License v3. The whole point of the the GPL is to make it so users of software could get source code to the software.
Section 3 of GPL 2 states that the company must either give the source to the user alongside the product (in which case the user has the source already), or the company must give to the user a written offer of source code. Note that if the second option is taken, the company is not obligated by the GPL itself to give the source code to the user. It is then only the written offer which obligates the company to give the source code to the user; only the written offer gives the user the right to the source code. Not the GPL itself.
Be sure to read the top comment where someone who claims to have worked for the company provides some inside information.
In my experience, this is quite common when the development of hardware is viewed as a cost center and is outsourced to various providers and teams. Those providers and teams churn a lot and nobody who worked on that is likely still involved with the company via contracts or direct employment.
Front line support people aren’t equipped to respond to these requests. If you’re lucky they’ll get bounced around internally while project managers play hot potato with the e-mail until it gets forgotten. You might get lucky if you go the corporate legal route, but more likely is that the lawyers will do the math on the likelihood of you causing them actual legal trouble for anything and decide it’s best to ignore it.
When I worked at a company that had a history of GPL drama one of the first things I did was enforce a rule that every release had a GPL tarball that was archived and backed up. We educated support people on where to forward requests. I handled them myself. 7 out 10 times, the person on the other end was angry because they assumed the GPL entitled them to all of our source code and they were disappointed when they only found GPL code in the tarball. It really opened my eyes to some of the craziness you get exposed to with these requests (though clearly not the polite and informed request in this Reddit thread) which is probably another reason why support staff are uneasy about engaging with these requests.
> 7 out 10 times, the person on the other end was angry because they assumed the GPL entitled them to all of our source code and they were disappointed when they only found GPL code in the tarball.
Well, if your non-GPL code was directly linked to, or closely interoperated with, any GPL code, those users would have been right.
As far as I understand it, Richard Stallman has gotten his view about linking from FSF’s lawyers, who has advised the FSF about what does and does not count as a “derived work”, in the sense of US copyright law.
If you want to argue that the FSF’s lawyers are wrong, please provide more detailed, and hopefully referenced, arguments (as opposed to plain assertions).
FSF has opinions but not case law - anyone else's opinion is as valid, there's no citation because no court has ruled that dynamic linking is or isn't a derivative work.
You have to construct your own view based on existing statute and vaguely related cases.
Google LLC v. Oracle America, Inc., 593 U.S. 1 (2021) is not a pro-FSF opinion.
Whether linking (dynamic or not) is a derivative work is defined by things like incorporation, similarity, and creative expression.
I think the FSF view is unreasonably confident in its public opinions where the current law is that each potential infraction is going to be decided on a case by case basis. Read 17 USC 101 for yourself and square that with FSF/Stallman opinions.
There's too much nuance to have a stance about what happens when you link a program. "It depends" is the only thing you can say.
>Google LLC v. Oracle America, Inc., 593 U.S. 1 (2021)
does not apply to the linking of GPLed code. Google copied just the application programming interfaces and then supplied their own code that they wrote themselves.
if you link to a GPL library you are including their copyrighted code, even if the API that GNU uses did not originate with them but came from POSIX or similar.
I would point towards Oracle v. Rimini, where the Ninth Circuit has specifically ruled (inside a complex and yet-unresolved case) that a system built to interoperate with a copyrighted program does not constitute a derivative work of that program. (https://cdn.ca9.uscourts.gov/datastore/opinions/2024/12/16/2...)
They reference a less on point but better known case (https://en.wikipedia.org/wiki/Lewis_Galoob_Toys,_Inc._v._Nin...., for some reason you have to manually add the period at the end of the link) about whether NES cheat cartridges were copyright infringement. If a work that directly links to and interoperates with a program is a derivative work of that program, the Game Genie really was illegal after all. To me that doesn't seem right, and given the FSF's general opinion on console restrictions (https://www.fsf.org/bulletin/2025/winter/new-nintendo-drm-ba...) I kinda feel like they'd have to agree.
On some sites it's possible to work around this type of linkification bug by percent-encoding the last character (percent symbol followed by 2 hex digits representing the ASCII character):
i don't see how either of those cases applies to the FSF and GNU's attitude on library linking; in neither case were they creating a combined derivative work.
if I make an ai driven viewscreen that you can stick your paperback book into and it gives you a better reading experience of the book, your paperback book is still in there and you can take it out. My viewscreen may not work without the book, but it hasn't merged/modified the book with anything.
Not the kernel, but LGPL libraries do have relevant carveouts. And if you've ever heard RMS speak, he is extremely particular and does understand the nuances of all this.
As always, the solution is to contact their legal department, preferably via a lawyer. Engineers and support staff are not going to risk their jobs making legal decisions about giving away company property.
The FSF could help a lot here by publishing demand letter templates outlining the statutory and precedential basis for license enforcement and recovery of damages.
But it's the company's legal department which would evaluate that claim. Because it's a legal claim. Licenses aren't magic spells, they're social agreements and non-executive employees don't want to get in trouble for making executive decisions.
That really depends. A company can still own the copyright to the code that they’ve written, even if it’s licensed with GPL. It’s an asset that is transferred if the company is sold, etc, so yes, it’s actually company property.
The GPL grants rights to use and distribute, but does not grant ownership. It’s not suddenly in the public domain.
Yeah there are are startups where head guys don’t know that and developers jump the gun because they feel like they’re ones that have the best understanding of the issue at hand.
I agree that a front-line CSR or even engineer is not likely the right person, but surely then the responsible action is to redirect the request to the responsible department or person?
Absolutely, and companies that routinely get requests like this train customer service agents on specific trigger words like "license" or "GDPR" that must be redirected. Without that training, it's not obvious why "it's GPLv2 licensed" is more compelling than the last customer's argument that the device warranty obligates you to drop everything and immediately fix the minor UI bug they reported.
I get mad triggered by software license violation discussions.
Please for the love of all that the FSF thinks is holy - just file a damn lawsuit if you are telling me they are violating the law. State your claim and have a court sort it out.
It costs hundreds of dollars. For a medical device? Seems like a good deal.
What's their basis for sending the emails then? If not one of legal standing in copyright/contract law?
Edit: My point is this is just another one of many annoying people you have to deal with who will email you alleging all sorts of legal violations, who don't themselves understand anything about the claims they are making.
This will probably dox me but I'm going to win a federal discrimination case against a university, with nothing but GPT5.x and Claude, and some filing fees. I'm no dummy but I'm not a genius. I barely got through the Advent of Code 2025 problems with a mess of spaghetti.
In my country people have a common law right to enforce the law themselves without having to pay legal fees. In America it's a statutory right I believe.
The risks of getting a costs order against me are higher than 0% but if I lose narrowly I won't be paying anything.
This is a fantasy. OK, well, if the intent is to waste time and lose a lawsuit, sure, a few hundred dollars will give you that experience. In the real world, no way. A single deposition can cost many times that figure.
You can choose to disagree, of course. My guess is that you have never done this and you have never been involved in a nontrivial legal dispute outside, perhaps, small claims court. You probably don't even own a nontrivial business. Not one person running a business would ever suggest a lawsuit could cost a few hundred dollars.
Like I said, in the real world things are different. I know people who have burned through over $50K in seemingly simple cases (one of them self-represented) only to bow out once they realized they only scratched the surface. In one case they went broke, had to sell their home to pay for the losses and move to a lower cost state just to survive. Tragic. And, BTW, they didn't lose the case. They just got to a point, tens of thousands of dollars later, where they simply had to drop it or face ending-up in a far worse situation.
When I was much younger (and really stupid as most young know-it-alls are) I decided to go after a company that owed me $100K in contractually agreed-upon consulting fees. They had already paid me over a million dollars over a couple of years, so this was not about a little $100K contract.
There was a change in management and they simply decided not to pay vendors. They did this as the simplest method (aside from laying people off) to improve financials. The new CEO and his wife also happened to own a law practice.
So, I hired an attorney (no way to do this on your own for $400). $11K later I finally understood that the balance of power was not in my favor. I may have won. It may have cost me somewhere around $75K to do so.
However, then the other reality would kick in: Collecting. Yup. Collecting was probably going to cost money and maybe even another lawsuit. Not to mention the time, measured in years, for the full experience. Not to mention the real potential of them filing for bankruptcy to gift me the experience of using my judgement as rough toilet paper.
In fact, that is precisely what they did about 18 months later to other vendors, who, like me, where chasing payment. They took a year to transfer all assets to a new corporation. When the original corporation had no assets whatsoever, the went ahead and filed BK and told everyone to go shove their judgements (if any).
I was actually glad that I only burned $12K to learn an important lesson: The legal path is only viable when you are talking about going up against an equal. Like anything, there are exceptions to this, however, in general, this is the way the real world works.
Still don't believe me? If you happen to be a budding entrepreneur looking for investors, do this: During your meeting, tell them that you are not concerned about lawsuits because they can be sorted with $405. Don't blink or you'll miss to witness just how quickly they leave the room. Really.
> The Copyright Claims Board (CCB)
is available to resolve copyright disputes of a relatively low economic value and provides an efficient, less expensive alternative to federal court.
If the only GPLed component used is the Linux kernel, you probably aren't entitled to any noteworthy source code. It's well established that using the kernel doesn't create a GPL requirement userspace software running on the same device, and the most likely arrangement here is a completely-uncustomized kernel paired with an open-source userspace program that does all the interesting bits.
It's trivial in terms that it will cost them nothing, because it's very likely there are no changes to the kernel, or nothing of value nor commercially-sensitive anyway.
It's not trivial in terms of big company bureaucracy - this request will have to go through so many levels of red tape that they (correctly) decided not complying to random people's requests is more profitable.
I'm sure if you actually sue them then they will comply right away, because at that point paying for some engineer's time to tar up the source tree and send it to you now becomes cheaper than lawyer time.
But their analysis is correct in that nobody will waste time/money suing to get what is effectively a stock kernel they can get from the official source anyway. Which is why these complaints are also a bit stupid - they're not asking for anything of value or using the GPL to advance software freedom by freeing up some valuable code, they're just wasting both theirs and others' time asking for something they can already download directly.
> because it's very likely there are no changes to the kernel
That is a gratuitous assumption. My experience is, as long as there is the smallest custom hardware, you will have to make some tweaks here and there.

I'm sorry that the company which is making lots of money by using a copyrighted SW has to "waste" 200 dollars in some bureaucracy, printing and postage. But is the license of the SW they are using, and should abide by it.

How sure are you small tweaks create a derivative work? In your experience.
Let me guess. Omnipod. They've had some pretty bad recalls too. Never in a lifetime would I trust my well-being to their p.o.s. hardware / software combo. Apologies that person in this thread that worked there, but I hope you are working for a better company now.
My point is: they could have left it out. There are not that many manufacturers of insulin pumps and there is only one that the title could have conceivably applied to.
Since a company building it themselves hasn't gotten it in the form of a binary from someone else that they're just passing along to you and their use is commercial, they don't satisfy either condition of GPLv2 3(c), but they'd need to satisfy both in order to be able to exercise that option.
Oh well. The whole thing has already been reverse engineered. Look up Loop or Trio or OpenAPS. Diabetic companies like Insulet have been very lax when it’s come to the hacking of their devices. This isn’t really that big a deal. What we need right now is help REing the Omnipod 5
I’m aware of a few people working on REing the Omnipod 5. The furthest issue that I have seen is that when a PDM/Omnipod 5 app signs into your insulet id, it gets a private key from the API which is stored in the keychain (and uses SSL pinning to prevent MiTM retrieval of the private key). When pairing with the pod they exchange public keys and then a derived key from the devices private key+pods public keys, but haven’t been able to get a copy of a private key yet to make further progress.
Anyway to follow the progress? I attended the Nightscout conference and asked around regarding this but no one really knew of any group to follow. Or really knew of the latest developments on this effort.
I am not aware of any public groups to follow the progress, I have just met a few people on the Loop Zulip and have talked with them every few months whenever people have time to look into it.
I'm thinking we probably need to get more organized and start picking up the pace with this. There are rumors, which of course I am not sure how credible, but word is that the Dash will be discontinued soon. Maybe we can add another channel to the Zulip to try to get things moving.
It seems to use the play integrity API when communicating with Insulet's servers which provide a private key to the PDM/app once it was registered with the user's account. However since the Pod doesn't have access to the internet, it has no way to check the play integrity signature AFAIK, so instead it checks that the certificate that the PDM/app presents to it is issued from the cert chain that it trusts.
Not all though, I've been looking at Minimed pump reverse engineering (which would be just reading glucose data, not controlling the pump), and that's not solved yet, at least not for the 780G. But I hope it will be, and perhaps I'll be able to contribute.
I don't work for Medtronic. But it's extremely unlikely that will happen. It's not merely a matter of reverse engineering -- after the original medtronic "hack" / reverse engineer efforts (the ones that lead to the original openAPS system being developed) the FDA put out new guidance on cybersecurity protections for insulin pumps.
The communication between your phone/pump or glucose sensor/pump is encrypted now for all newer devices.
> Diabetic companies like Insulet have been very lax when it’s come to the hacking of their devices
No it's true. Companies like Insulet and Dexcom could send out lawsuits to all the open source projects out there that involved REing. Dexcom's glucose share API was REed years ago, and Dexcom hasn't even tried updating or stopping the use of unofficial APIs. All I'm saying is that the companies really don't care at all.
So can someone tell me - a non-insulin-dependent individual - why would an insulin pump need to be (controlled by?) a phone (in this case, the Nuu phone referenced)?
Surely there is a way to cheaply obtain bluetooth and a controller without saying "we'll just use this already existing hardware - that happens to be a whole-ass phone - because it's $5 from China"?
Kinda feels like that just screams data-stealing, regardless of where it was made.
Security… The PDM is walled off completely, it cant install apps, its not on wifi, you cant change any settings. The issue is that a PDM technically could easily kill you, by giving you a lethal dose of insulin.
Funny thing is that the newer Omnipod 5 from the same company works with regular phones now, but only in th US.
Until recently, if you offered a pump that _could_ be controlled by another device (such as a phone) you would have to offer your own "controller" device, even if 99.9% of your customers have a phone already.
So, this companion device is kind of a thing that Insulet had to release. You'll see this with CGM's too -- there's a small companion device sold with the Dexcom G7 (the "controller"), even though everyone just uses their phone.
This is kind of a regulatory quirk; basically from the FDA's point of view you had to have a complete standalone system, that did not include the phone, in order to be able to prescribe it. I think they do not require companion devices any more, it's OK to release something that requires the user to have a phone.
"we plan on users having a phone to connect to it and use primarily. FDA requires a primary/backup. well it's already phone-controlled, go find a phone that works with it. needs to be cheap, cuz no one will really use it anyway"
That makes a little more sense. I was imagining the development process involving both devices, rather than one device first, then determining what the second would be later.
One thing is that you need to tell the insulin pump when you eat food so it can deliver insulin to cover the food. I bet that is a lot easier in an app than some separate controller device.
Insulin pumps are paired with glucose monitor. I bet it is handy to check glucose levels to make things are stable and correct if off.
I recall idly looking through the manual of our Bosch dishwasher when it was delivered and seeing that they offered to share GPL'ed source code from the machine's embedded guts. I thought to myself, "that's kind of interesting, I'll take them up on that". So I emailed the address they provided for this purpose. I got an auto email back saying, effectively, "No. You're not an authorised person, we don't recognise your email address, we don't know who you are, we're not going to talk to you."
Oh well. Big Corp doing what Big Corps do. Paying lip service to legal requirements, but reluctantly and with barriers that would no doubt take a lot of time and money to even try and break down.
I was troubled by my own comment. How exactly did Bosch handle this? I went back and checked and in fact the rejection email came from their email server, it was an "access denied" type email that I originally misinterpreted as a "you don't have access" type message leaving me annoyed but really I took away and remembered a wrong impression. Looking more carefully, the message doesn't mean anything subtle, it just means the email address (oss-request@bshg.com for the record) doesn't exist. Which is bad, but not nearly as bad as I portrayed it above. Apologies (for the record) to Bosch.
Why is this relevant for understanding how the IP works or even tweaking it? Whatever is relevant for that matter will most certainly not be a modification to the Linux kernel that the android system is running. It will not fall under the GPL that the kernel is licensed under. Can someone explain why this dispute is worth having beyond a theoretical legal debate on whether they should hand out the particular source tree from which their kernel was built (if they even built it)?
I'm sorry you didn't get a response yet. I'm not a lawyer and have no legal training but it seems to boil down to this:
It's part of the debate of whether (1) GPL is a contract, (2) GPL can be enforced by non-parties, (3) How Fair Use applies, (4) Methods to bully/shame companies to give up source code ...? (5) Who the actual parties involved are if the actual rights holder (Linux Kernel) tries to sue someone. (First Sale doctrine might apply).
TL;DR: Not the FSF, but SFC; email compliance@sfconservancy.org
The dominant legal theory is that the GPL can only be enforced by the party holding the copyright. SFC's lawsuit against Vizio is strategically trying to establish precedent changing that; establishing that end-users are "third party beneficiaries" under the GPL, so others can enforce the GPL; but for now the copyright holder is the only one who can enforce it.
So the FSF could only take it up if the violation is on projects that do copyright-assignment to the FSF (i.e.: most GNU stuff). If you do find a violation of GNU stuff, the process is "email license-violation@gnu.org". I do not know what process Craig and Krzysztof use when triaging reports and deciding what to pursue.
Many Linux-kernel contributors (also, SFC member projects such as OpenWrt, Git, Qemu) have assigned their copyright to SFC or named SFC as their legal representative (also, SFC member projects; so SFC can take up something like this. Similarly, you can report violations to them by emailing compliance@sfconservancy.org (see https://sfconservancy.org/copyleft-compliance/help.html for more info).
Now, SFC is aware of more violations than they could ever possibly pursue, so they're strategic about pursuing ones that are high-impact. I'm not sure how they decide that. But I can say that medical devices are near-and-dear to them, between executive-director Karen Sandler's implanted defibrillator and policy-fellow Bradley Kühn's blood glucose monitor.
It shocks me how much comments, here in HACKER news, are something like:
"Why do you want the source code?! leave it alone! Don't touch it, is unsafe! Big Pharma companies know much better than you what they do!"
REALLY?! REALLY?!
I'm not saying, go changing the SW like crazy. Is clear it can kill you. But this "anybody who is not a mega pharma company is absolutely unable to do anything right, you will absolutely kill yourself if you look at the code" that is just... idk... so low.
It may be named hacker news, but boy, many people here are not remotely near what I would call a hacker...
"Agency is dangerous, please take away my(and by extension, everyone's) agency to hurt myself!" is a sentiment that's somehow gained a lot of traction everywhere. The People yearn for the accountability sink.
> This honestly disgusts me. GPL violations are already bad on their own, but on a medical device? That me, and thousands of people rely on to stay alive?
Disgusting is not respecting the producers who put together the device that wouldn’t exist otherwise, leaving thousands of people in pain or death.
What a remarkable stalking horse to try and kneecap right-to-repair by arguing "Please, think of the chil^H^H^H^Hhackers!"
You wouldn't download a CAR, would you? You wouldn't hack your own INSULIN pump, would you?
Face it: If it's GPL and vulnerable to interference, responsibility is squarely on the manufacturer and the fastest death-free way to prove it. If it's GPL and modified by the owner, fuck off.
The normal response to a company importing illegal products is to seize them at the border, destroy them, and, optionally, send the importer a big fine. This is already an established process.
This is technically not true. It is an oversimplification of the common case, but what actually normally should happen is that:
1. The GPL requires the company to send the user a written offer of source code.
2. The user uses this offer to request the source code from the company.
3. If the user does not receive the source code, the user can sue the company for not honoring its promises, i.e. the offer of source code. This is not a GPL violation; it is a straight contract violation; the contract in this case being the explicit offer of source code, and not the GPL.
Note that all this is completely off the rails if the user does not receive a written offer of source code in the first place. In this case, the user has no right to source code, since the user did not receive an offer for source code.
However, the copyright holders can immediately sue the company for violating the GPL, since the company did not send a written offer of source code to the user. It does not matter if the company does or does not send the source code to the user; the fact that the company did not send a written offer to the user in the first place is by itself a GPL violation.
