The argument regarding the specific case of AI-generated images of real actors makes sense, but the headline overgeneralizes hugely.
If you write a book about carpentry, and someone checks that book out from the library, reads it, learns how to do carpentry from it, and goes into the carpentry business, they do not owe you a share of their profits.
It's nice if they give you credit. But they do not owe you a revenue stream.
If they are a robot, the same remains true.
