Is it though? That is (or was, and should be again) publicly accessible information that was created over the years by random internet users. I refuse the notion that an American company can “own it” just because they ran the servers. Sure they can hold copyright for their frontend, name and whatever. But posts and comments, no way.

Of course it would be dumb for someone under US jurisdiction but we’ll see how much an international DMCA claim is worth considering the current relations.
