I'm pretty firmly on the side of "large-scale analysis of content that's accessible to the public should be entirely outside the scope of copyright, regardless of what one does with the output", even though I also sympathize with artists that see generative AI as a potentially existential threat to their careers. But I'm curious if Getty is actually going to make meaningful payments to the creators of the images that went into the training set, or if this is more of a "we could continue to pay our existing royalties to content creators, or we could keep most of the money for ourselves by selling access to a model trained on that content" type of situation.
