Technically, they are. However the costs of legal pursuit vastly overshadows any potential profits such endeavor would bring to the company suing. Especially for such dead IP like JJ is (and I'll consider it dead until Epic starts actually doing something meaningful with it again outside Fortnite easter eggs and vague tweets).

Nintendo, as I've said, is an exception, not the norm. They can afford the loses legal actions against youtubers and fan creators it would bring them (well, financial ones, at least) so they're doing for some inane reason. And before someone brings up Japanese copyright law, well, Capcom and Sega are Japanese companies as well and they're not involved in such BS.

I don't think Nintendo will be able to do it forever though. Eventually the PR loss of such moves will start driving people away from their products and towards those of their competitors who aren't doing that copywrong idiocy.
