And I'm amazed I have to spell this out for you: are you trying to fight for artists who benefit from copyright (definitionally non-proletarians in that action) or strike a pillar of capitalism at it's base?
You're just circuitously defending some of the exact same, and a much larger, set of wealthy corporations: those that benefit from copyright as it is. I'm defending absolutely no capitalist company, I'm arguing to strategically push for their intercompany fighting to bring us closer to an end of capitalism. And right now that means not needlessly fighting for Disney against the AI companies.
Who are these artists who need to be defended from proletarianization above the fight for communism? In what way is that advancing our cause?
