The commercial advantage is that it levels the playing field: If I create a library that can be used for a website and release it as FOSS under a license that is not as restrictive as the AGPL, I basically create a disadvantage to my own business: Another company could use my code in a closed service and thus benefit from my work without giving me and their users the courtesy of benefiting from their work in return.

I write commercial GPL software and will, in my next refactor, license certain parts of the software as AGPL. An example would be a library that connects an invoicing system to an online payment processor (ie. creates a full checkout process for invoice X at amount Y). I have a lot of work invested in the code (basically 5 years of my life) and the better and more reusable I make it, the easier it is to just retool it for another application. I would naturally love to see websites utilize the code, even if it is just in a SaaS setting. But since it is my work, I have decided to set the rules and if people want to use it, I think it's fair to ask that they should promote the same liberties that they received from me.

Good answer, I'm in a similar boat in some ways.

I would be more concerned about the "viral" nature of the GPL (I assume this applies to AGPL as well) i.e I would be happy to use AGPL code in my application and release any modifications I make (or create AGPL code and have others do the same for me) but there are parts of my applications that I really wouldn't want to have to release (because they are very industry specific and would be useful to competitors without modification and not useful at all to the general populance).

A similar license but one based on LGPL would be preferable.

If you're the developer of the AGPL licensed code, there's no problem in using it combined proprietary software. As the copyright owner, you don't need a license to use your own code.

Of course, if you accept patches from others, that's no longer true, unless if "force" people to dual license their code, with the second license being an exception just for you.

Of course, there is no 'viral' nature of the GPL, please don't spread FUD like that. The fact that your licenses have to be legally compatible and thus using GPL code in your software can be a restriction that benefits using more free licenses yourself does not equal a viral infection. The same would be true for proprietary licenses, just in a different direction.

A similar license based on the LGPL wouldn't make sense. The LGPL is basically the GPL with an addition that says that you don't have to be that strict on what license the software you use it in uses.

Right , hence why I used quotation marks around the word viral.

Problem is I'm not enough of a lawyer to know what would and wouldn't be compatible with the GPL (and confident enough to tell other stakeholders). With something like a BSD license it's easier to point to concrete examples of it's co existance (OS X for example).

Well, the GNU Project has a pretty extensive list[1], so I'm not sure whether you just haven't seen this yet, or whether there is a different concern here.

As far as I can tell all of those licenses are some variation of libre licenses, I need something that's compatible with a license that says "this is ours , nobody else can have it".

The reason we need to use a license like that and not a libre license is that some of our software is very niche and would only be useful to a handful of companies around the world.

It's quite likely that none of these other companies employ any programmers at all bar the occasional contractor. Basically we are trying to disrupt an industry (in a small way) by getting more efficiency by doing stuff through tech that they are doing by employing legions of admin staff and using the old-boys network (it's a very old school industry).

If the source for certain parts of our software was available to them then they would most likely simply use it (employing an Indian contractor or similar for a couple of weeks to set it up) to wipe out our advantage and not contribute much if anything back to us.

There are however other parts of the software that could be generally useful to a wide number of people who are much more likely to contribute code back.

In that case, you probably want to consult a lawyer beforehand anyhow. If you're working on something truly disruptive and innovative to an established market, software licenses might be your smallest concern.
