SSPL is a bit more restrictive, but politics also have a lot to do with it. "Open Source" is just a term, technically anyone could call their license open source, but most people only consider a license open source if the OSI (a foundation) specifically approves it. Mongo tried and failed to get SSPL approved by OSI: https://blog.tidelift.com/what-i-learned-from-the-server-sid...

Interesting. According to the article, it seems like the biggest complaint was that Mongo was a for-profit company and couldn’t be trusted? I agree that for-profit companies can’t be trusted, but I’m not sure I agree with the statement “that’s not open source because the license was written by a for-profit company”.

That article is obfuscating why the license was going to be rejected by the OSI. The OSI has as part of their definition of open-source that there can be no field of use discriminators. It had nothing to do with the fact that it was drafted by a commercial company. OSI has approved plenty of licenses drafted by for-profit companies (e.g. Intel, IBM, Microsoft.)

How come AGPL doesn't run afoul of #10 of the OSD definition, which is:

> 10. License Must Be Technology-Neutral

> No provision of the license may be predicated on any individual technology or style of interface.

Under AGPLv3 if I have AGPLv3 code on a computer and users can interact with it the requirements depend on the technology used by the users to interact with the program.

It had a provision that only applies to users who are "interacting with the remotely through a computer network".

So...if my users are at the same location as the server and interacting through a command line interface on serial terminals those provisions do not apply.

I want to add a few more terminals in a nearby room but don't want to actually run serial lines from all of them to the server. Instead I run ethernet to the room the new terminals will be in, and at each terminal place an RPi with the terminal connected to the RPi and the RPi connected to ethernet. The RPi runs software that connects to the server via ssh and then exposes that ssh session on the terminal so they can use the command line interface to that AGPL program.

Now the users are interacting with the server via a computer network and so those provisions of AGPL might now apply, depending on whether or not this counts as interacting "remotely".

Same thing but now I provide an app that users can run on their phones that that makes a hard coded connection to my server and runs a terminal emulator over that to a terminal session on the server, where the users can use the AGPL program. There doesn't seem any question that this is now definitely remote, and it is over a computer network, so those AGPL provisions now definitely apply.

And so we have essentially one thing, users using a terminal interface to interact with an AGPL command line program on my server, where what license provisions apply between me and any given user depends on just what technology is used to carry their typed text between their keyboard and my server, and to carry the program output text between my server and their display.

That provision is intended to exclude licenses that say things like "you must show a modal GUI window crediting this software" which would exclude the software from being used in a server application, library or command-line interface. Or a clause like "you must provide a copy of this software on a zip-disk if asked", which over time would become increasingly hard to do.

The AGPLv3 is not predicated on a particular technology or interface so it doesn't run afoul of this. You can use it in networked software, or un-networked software. If a license said something like "you cannot use this for software that users interact with over a network" then it would violate this principle.

Thanks. That makes sense.
