Copyright is not gatekeeping. It is just how artists earn for their work that is intended for a mass (or commercial) audience.
Artists are, in general, extremely keen for there to be more art, more artists and more opportunities for artists. It’s not inconsistent with them wanting those artists to do their own work; indeed that is an essential part of it.
I'm not arguing about "there being more art"
I'm saying artists don't want anyone doing *the same art they do*
GPL ideal gives everyone ability to copy-paste and expand anything, with only obligation to allow everyone to do the same to you. Artists culture is far removed from that

even more than that, I see people arguing for MIT(!) to lessen the legal burden on fellow programmers
that's the kind of cultural difference I want to point out
