There's still that pesky clause in copyrighting that says it has to be created by a human, so until it gets clarified legally everything created by AI is pretty much royalty free, zero copyright protection, you can steal it, take it, use it as you please, and no one can stop you... Unless it contains something pulled from copyrighted art.
There are currently several suits filed, and more coming. Getty is suing one after finding portions of their "real" copyrighted works, as well as portions of their watermark embedded in AI created images (nothing like waving a flag that says it was stolen). Another group of creators is filing a suit against Microsoft and their AI partners for infringement. A comic book creator had his copyright revoked after they learned it was AI generated. It's is going to be a legal nightmare, and it's only the beginning. Anyone caught using AI generated art with copyrighted components for profit could suffer the same legal repercussions as copying Disney characters, so even the crafters and weekend hobbyists need to tread lightly. I see in the Adobe Q&A they state all theirs comes from open source, but that'll only get them so far in trying to keep up with all the ones who already crossed that line by using massive amounts of copyrighted works. Of those who rely on AI to "say" they're an artist, how many will he happy with the limitations of that? It's going to be interesting to see how this all plays out.
Sure glad I can create my own art
