Who's to say what we'll find important down the line? Quite often what seems mundane and not worth the effort to copy or maintain turns out, in hindsight, to have true value. One of if not the most important insights in studying previous cultures comes from going through their trash heaps. Similarly, while they could seem pointless, a lot of this content could provide unique insight on our own culture down the line that 'valuable' pieces saved and curated can't.
See, for example, some of the BBC shows that got deleted because magnetic tape was too valuable to just store popular culture on.
Recently the BBC has been asking people to search attics and sheds for home recordings (taped from tv or radio broadcast) or "lost" tape (probably meant for erasure and reuse that got ahem 'lost' on the way and ended up in a BBC technician's collection).
I find it weird that mega had petabytes of poorly de-duped content (very many copies of the same pirated movie in different rips) yet we're talking about deleting content because, well, because.
Having said that I'm not giving them any money to keep it archived let alone online so perhaps I need to shut up or put up.
