I just think it’s stealing, and honestly not that cool once you’ve seen it once or twice, and given the ramifications for humanity.
I know of no other type of theft that results in more of something existing in the world. Stealing deprives someone of something; copying data (from training an AI all the way to pedestrian "YoU wOuLdN'T DoWnLoAd a cAr" early-aughts file-sharing) decreases scarcity, it doesn't increase it.
