This doesn't do much for the argument that artists only do art for money. Everyone knows what happens to free use art, same as what happens to FOSS: corpos bundle it up and sell it back to people.

By the way, I do know a lot of artists that just give their work away for free. Hell, any Burn is just a bunch of free art that usually gets lit on fire or destroyed after a week. There's also graffiti art which is uncompensated and usually painted over within a month.
