IMO the issue is that an artist does not have copyright on a style.

"Salvador Dali style painting" does not violate Dali's copyright any more than Dali violated the copyright of his surrealist influences.

It is like saying music made with guitar/bass/drums/vocals violates The Beatles copyright. No matter how remote, the influence of The Beatles is in the "training data" at this point with that configuration.

Stable Diffusion would have nothing on a band like Oasis violating The Beatles copyright if we want to go down this road of artist copyrighting a style. It is nonsense.
