InfoWorld has an interesting story on GPL’s decline (might be a strong word) in favor of some more permissive licenses, notably Apache, MIT, and BSD. I think this part hits the main deciding factor:
Originally associated with variants of Unix, these “permissive” licenses took their names from the universities at Berkeley and Massachusetts: the BSD and MIT licenses. These licenses allow you to do almost anything with the associated software, including making it closed, proprietary software to which the four freedoms no longer apply. This is also a source of controversy, as some people consider it wrong to take open source software and prevent others in the future from using, studying, modifying, and distributing it.
Many corporations out of licensing concerns forbid GPL, rational or not. In my experience if you want to keep your project open to as many enterprise and corporate uses as possible, BSD, MIT or Apache is your best bet. I don’t think many these days still forbid all open source. Some still forbid GPL. They will use GPL licensed software, just not the code.
Deciding what license you pick is an important part of any software project.
