Social support (or we can even call it "[corporate] social responsibility") is a political question/problem/thing.
Endless iterations of the discussion about how copyright should/shouldn't be are meaningless without considering the larger social context.
The vast majority of creators (artists!?) are not compensated at all, and the users' (content consumers'? the public's?) attention is already 100% fully saturated.
So GenAI chrurning out more kitsch hardly changes that. (It got popular when it was novel, and ... that was it for now. And it became one more brush in the evergrowing workshop.)
And if/when a company creates a product out of it, then that product needs to be scrutinized and we should consider the ethical, social, and political problems. (Because ... politics is a blunt tool whereas ethics is as infinitely nuanced as we make it, whereas actual social considerations ought to be pragmatic and fair.)
And that's the problem. Users benefit from cheaper access to customized content. (In other words, arguably it's a net positive thing that they can - for example - ask some GenAI tool to make them a nice picture for their friend's birthday.) So what's the cost of this? Does it make some people jobless? Is that good or bad? (Is it good that plant breeding programs, fertilizers, tractors, and irrigation systems made a lot of agricultural workers jobless? Well, in some sense yes as allows a few people to feed many, freeing up time for others to become doctors and artists. In some sense bad, because our current socioeconomic system does not provide real social support - despite enormous redistribution of GDP. [Because brutal inefficiencies in allocation of that surplus. And that's again a political problem.])
... and of course here the status quo bias leads to "technological progress chipping away at inefficiencies" in a capitalist reality translates to "even more things get commoditized", and that in turn in the current shitty socioeconomic system equals "lots of externalities are not priced in, and lots of people are forced to drastically change their lives to adjust to new prices" (ie. price of their labor and/or products going down, so they need to change jobs, yet they barely get any support for doing so) ... and of course ethically it's bad that most people virtually uncritically accept and enjoy the results of progress (new products and services) without giving a fuck about the costs.
