This then would put the responsibility on the creator, not the software. If I use a prompt "Mickey Mouse fighting Thanos" then the images produced are clearly derivative. But is this fair use? There's plenty of fan art out there like that. In fact, I typed that string into google and got fan artwork of Mickey as Thanos and the infinity stones are different media centers that Disney controls[0]. Making the image quite a high quality parity. I'm not a lawyer, but I don't feel like this image should be illegal. If so, doesn't that make this conversation far more complex than what you're writing here? I'd agree if I was trying to sell pictures of Mickey Mouse and claim to be Disney (and that there was no case for parody), but this does seem like a really hard line to draw and I don't think people are being honest about that.
