I've always wondered why we don't see any platforms just remove the media while leaving the metadata, comments, ratings, etc intact. Like, is there some legal requirement that the idea itself has to be hard to find, or is it okay to just remove the media and let people keep discussing it?
It implies the service is lacking something, that it's deficient in specific tangible things you want but they don't have.
A generic 404 for something you don't even know exists won't leave a `video_title` sized hole in your heart and chip on your shoulder, and won't give competitors opportunities to serve your needs instead.
Legal requirement - probably not. Econophysical constraint - betcha. They mostly don't care about the discussion, or the content, or the idea, they care about keeping your eyeballs within a given rectangle until a bell rings.
Name itself might be what is legally required to be taken down.
