Not true, legality is disputable in many ways. Never steal and edit AI art that someone generated because if its edited AI Art you can be in major trouble.
AI art may not adhere to DMCA compliance from what I can tell but the edits do. Which have to be inside the AI art, see what I'm going for here? So if I make AI Art, edit it and then get the stuff yoinked by some retard just screams free money for me. And since I made the thing I can easily proof it. Usually won't happen because the people who're against AI art are mostly children but you can easily sue the parents for being retards and not taking care of the kid for making stupid ass decisions like not adhering to copyright protection laws and literally stealing assets form developers. I don't know what for but its retarded decisions so it doesn't have to make sense. Just means free money on my end.
It goes without saying that legalities do not apply the same from country to country. As a hypothetical example, when I make AI Art in a country where you cannot steal it because its protected under our copyright, but you steal it from your country that don't then you're in trouble as well because you're stealing my product that I made in lawful ways. So in a way you aren't even allowed to look at my art since its not allowed in your country, if you get what I mean. However, if I edit my art then the legality is disputed and you are allowed to buy it since it complies to your laws too, which means its protected under both our respective laws ensuring protection on my end and allowing you to purchase and enjoy the product.
