There are already anti-AI licenses out there. If you didn’t license your stuff with that in mind that’s on you. Deep learning models have been around for a lot longer than GPT 3 or anything that’s happened in the current news cycle. They have needed training data for that long too. It was predictable stuff like this would happen eventually, and if you didn’t notice in time it’s because you haven’t been paying attention.
You don’t get to dictate what’s right and wrong. As far as I am concerned all copyright is wrong and dumb, but the law is what the law is. Obviously not everyone shares my opinion and not everyone shares yours.
Whether an artist is involved or not it’s still a transformative use.
