The more interesting or sensitive stuff seems to be getting taken down increasingly quickly. At this point, I'd prefer not to watch something in the first place than to watch it and be unable to refer back to it later when I'm reminded of it by something else. I'm also motivated by the more general issue of cultural vandalism and activist agendas being pursued by tech and media companies, and I think that a system of decentralised offline backups provides the basis for a longer-term solution to this problem. Also, storage is incredibly cheap.
