And I have to say, it’s pretty telling that you saw my comment and took “unethical” for “illegal”. Your focus is clearly “this isn’t illegal, and here’s the evidence to support it”, rather than introspecting and seeing that legality isn’t tied to ethics in a lot of cases. Instead try looking at it from an ethics standpoint, you’ll find there’s a lot less to stand on supporting how models are created, of course trying to get every artist’s permission for using their images in a model would be incredibly difficult, so you instead support the “it’s not illegal” route, even though it’s clearly unethical.
Your whole comment here quite succinctly demonstrates that you truly don’t understand ethics. “licenses and permissions are irrelevant” is quite a way to put “I don’t care about your desires, imma do what I want as long as it’s legal”. It’s unethical, full stop. You should do some introspection as your ideas are harming others and your inability to see that is quite sad.
