OP's original comment called this stealing and this response is that the "obvious solution" is that the thief will pay their victim back after turning their stealing operation into a successful business. That is silly. Do people think that if the Pirate Bay is allowed to exist long enough that they will eventually start paying Hollywood Studios for new movies?
If you want to argue against OP in defense of these AI companies, argue why what they're doing isn't stealing or why what they're doing in the moment is justified. Don't say the stealing can be excused by some hypothetical and implied promise of future reparations.
EDIT: It's funny to respond to a comment asking for explanation of the downvotes only to be downvoted without explanation.
