I think they try to expand copyright from "protected expression" to "protected patterns and abstractions", or in other words "infringement without substantial similarity". Otherwise why would they sue AI companies? It makes no sense:

1. If I wanted a specific author, I would get the original works, it is easy. Even if I am cheap it is still much easier to pirate than use generative models. In fact AI is the worst infringement tool ever invented - it almost never reproduces faithfully, it is slow and expensive to use. Much more expensive than copying which is free, instant and makes perfect replicas.

2. If I wanted AI, it means I did not want the original, I wanted something Else. So why sue people who don't want the originals? The only reason to use AI is when you want to steer the process to generate something personalized. It is not to replace the original authors, if that is what I needed no amount of AI would be able to compare to the originals. If you look carefully almost all AI outputs get published in closed chat rooms, with a small fraction being shared online, and even then not in the same venues as the original authors. So the market substitution logic is flimsy.
