The “legal proof” part is a different argument. His picture is a generated picture so it contains none of the original pixels, it is merely the result of prompting the model with the original picture. Considering the way AI companies have so far successfully acted like they’re shielded from copyright law, he’s not exactly wrong. I would love to see him go to court over it and become extremely wrong in the process though.
It'll probably set a very bad precedent that fucks up copyright law in various ways (because we can't have anything nice in this timeline), but I'd like to see him get his ass beaten as well. Thankfully, removing watermarks is already illegal, so the courts can likely nail him on that and call it a day.
