Honestly I think that's why reddit is closing itself up too. Everyone sitting on a website like this might be sitting on a Ai training goldmine that can never be replicated.
I think "AI is takin' ooor contents!" is a convenient excuse to tighten the screws further. Having a Boogeyman in the form of technology that's already under worried discussion by press and politicians is a great way to convince users how super-super-serious the problem must be, and to blow a dog whistle at other companies to indicate they should so the same.
It's no coincidence that the first two companies to do this so actively and recently are both overvalued, not profitable, and don't actually directly produce any of the content on their platforms.
