If this is true (which I kinda doubt), is it going to matter to most people? Like you can't really tell the images used to train a model from the images it generates (if it's trained correctly), so I doubt the majority of people would care, like those who already use MJ for example. Training models on copyrighted data for academic research will be allowed, the models will be published, and good luck enforcing the licence; and here I'm talking about the worst case scenario where a court would find an image generated by AI to be derivative of another image in a pool of billions in a dataset (this goes way beyond any definition of derivative work for now).
