This will closely mimic van Gogh's style but nobody cares because style cannot be copyrighted in itself. So it draws a robot owl, which for the sake of this example, is a new character.
Zero copyright violations.
My point remains that AI users aren't going to aim for output that directly looks like an existing character. These artists are now intentionally doing that for the sake of the protest but this is not how AI is used. It's used to create new works or far-derived works.
