One failure mode of big projects using permissive
licenses is that someone can fork your code, make
some kind of change to it, keep that change to
themselves, and then turn around and sell the whole
thing. This could, in theory, pull resources away from
your project to their fork. So if you make your code
available under a copyleft license, you can head off
this whole cycle, again, in theory.
