US law only applies to the US, and what is legal is not the same as what is moral.

As for fair use, this is not the same as someone remixing or sampling songs, or writing fan fiction or satire or quoting works for criticism.

People do not want models trained on their creative works, so that someone else can make money using those models to produce similar creative works as a service for third parties.

While it is possible to create similar creative works -and I will grant that that could be a prima facie problem- it is also possible to make rather new creative works as well. Just like you can do by hand, you can interpolate and extrapolate from known starting points, and there is nothing stopping you coming up with something totally unique.
