Wow, really? So it’s essentially impossible to use this for proprietary software? I knew about the server stuff, but I didn’t think the AGPL bound compiled programs to the terms of the compiler.
If I use an AGPL text editor, does my written text also become APGL?
An (A)GPL text editor works, see for example Emacs, as the text created doesn't contain any part of the editor itself. But a compilers emits code which is based on your source and the compiler itself. Also, it usually links against a standard library which would be AGPL. So this makes your created executable AGPL unless there is an explicit excemption, as it is the case with GCC.
Probably more poignantly, it's not usable for open source projects that want to distribute their stuff under a license that's more permissive than the AGPL.
