Hi Jose,
Richard Stallman asked me the exact same question in 1995. ;)
It all comes down to the fact that I want people to be able to do
anything they want with my software including selling it to others.
I just don't care as long as I get credit (the currency of academics)
and you don't blame me when it erases your harddrive and/or all life
on this planet. :)
I don't want people to avoid using my work because they cannot extend
it without giving it back to the community. This would essentially
means that businesses would be much less likely to use my software.
I want the most leeway possible for people so that there is no excuse
not to use ANTLR (unless of course it sucks) ;)
[no general discussion of merit of GPL etc.. please. I have made my
decision to use BSD for ANTLR v3 etc... and it's final]
Regards,
Ter
