The position was never "individual artists should not own their work", the position was "Perpetual copyright is bad". You act like that's the same when it absolutely isn't.
AI isn't touching Disney because those companies know Disney has teeth. So they copy from all the individual artists who depend on their art to survive and act like that's not bad. I have seen people on this site argue for that actually, because 'it's like pirating a movie'. To which I say: Fuck off. It's not the same because one case takes from a rich as god company while the other takes directly from a worker. Sure, the worker might be providing furry porn but so what? They are fulfilling that societal demand and should be fairly compensated for it. If these AIs were taking exclusively corporate art and shitting out their slop, I would have no problem with that.
