Don't downvote this guy. He's mostly right. Creative works have copyright protections from the moment they are created. The relevant question is indeed if they have the relevant permissions for their use, not wether it had protections in the first place.
Maybe some surveillance camera footage is not sufficiently creative to get protections, but that's hardly going to be good for machine reinforcement learning.
I think that the ones who revolted against their preparatory enshittification aren't Reddit users anymore (hence why I'm here), and the ones who didn't revolt won't do it now either.
