They don’t have a right to extract art from artists… commission means pay for a piece up front, not after the fact. And on top of that you can only make digital copies cheaply.
Again they would not be “stillborn”. We’ve figured out crowdsourcing and popularity-based compensation (YT, patreon, etc.). You are just making statements without backing them up with readonable arguments.
Why would they when they’d have every right to take it for free?
Creative endeavours would be absolutely stillborn if only people wealthy enough to practice their craft could pursue the thing
