Adobe is planning for a post-regulation, post-biggest-lawsuit world for sure. All their steps show that they'll base their offering on their own commercial data - paying training license fees to stock images and artists.

Whether the amounts they pay would make licensing your work sensible or not, Adobe is surely assuming this will ultimately end up as Napster-to-Spotify transition.

If we end up "happily" (means legally as well) running these on customer level hardware, then the question won't be about credits of computation. It'll be about credits to use licensed work.
