Ah, this is obviously some strange usage of the word 'indisputably' that I wasn't previously aware of.

This model is trained from scratch using only public domain/CC0 and copyright images with specific permission for use: https://huggingface.co/Mitsua/mitsua-diffusion-one

Does it change anything?

If all the other models were deleted, and this was the only one left, and all future models also had to be similarly licensed, would it change even one single point?

Even if it was the only remaining model and this kind of licensing a requirement for all future work, artists would still be automated out of their highly skilled yet poorly paid profession. It still sucks. There's still no nice way to convey that.

> You built a commercial product on unlicensed data. Do you actually think the law is going to agree that that's fair use?

What do you think the Google search engine is, if not a commercial product built on unlicensed data?

The courts go both ways on this specific question with Google depending on the exact details, because nothing in law is as easy or simple as the clear-cut, goodies-vs.-baddies, black-and-white morality play you want this to be.

The fact that Stability AI have not yet been sued out of existence in a simple open-and-shut court case about copyright infringement ought to have demonstrated both this point, and also that the question "is this piracy?" is, in fact, disputable.
