I'm going to take the side of the IP argument based on whatever hurts big business most. If they want to "steal" from the little guy by locking everything up behind copyright (or patents or trademarks) then I will oppose it. If they want to "steal" from the little guy by ingesting his works into the AI machine then I will oppose it.

Notice how governments and companies became "worried" about AI when people were starting to emulate certain styles in the images generated. Suddenly they needed to be regulated and censored (even harder).
