In a world where copyleft licenses turn out to restrict only the small actors they were meant to empower, and don't apply to big bad-actor "AI" companies, what is the incentive to put your work out under a license that will only serve to make it a target for "AI" scraping?
With NFTs, we saw people taking their work private because putting something behind a clickwall/paywall was the only way to not be stolen for NFTs. I assume the same process will accelerate in an "AI" world.
