How is the ai supposed to know these watermarks aren't a style element? They're present in tens of thousands of input images, after all. Therefore, I'd say this is a bad example of an AI literally copying from one specific source. It's similar to it using Arial letters: they're everywhere in the source data.
The i stands for imagination/ignorance at the moment. Intelligence (or something indistinguishable from it) doesn't seem too far away but isn't here yet.
So all we have is a dumb bot that can appropriate styles and ideas. Revolutionary, but not quite to the extent needed to sue it for copyright.
