GPL means you can have the software+source for free and make changes to it. But, if you sell or redistribute it (which you can also do), you have to give people the source code with any improvements you made to it also.
AGPL is the same, but you also have to give people the source if they’re accessing it behind a web service or something (i.e. making use of it without technically “receiving” the underlying software).
Yeah, no particular reason. Either it was already licensed GPL3 with multiple authors and not enough reason to “upgrade” to justify the difficulty that entails of consulting with everyone, or it’s a type of software where there’s basically no difference, or they’re just not aware of it.
So aGPL is basically just better gpl.
Why do people mainly use GPL then? Just don’t know it exists?
