That's the funny thing, isn't it? Some people (not me, of course) probably spend a good chunk of change on seedboxes, hosting, Plex/Emby, etc., more than the cost of single subscription. But they get so much more for that money.
Plus, at this point it's archival, as there's no legit way to get tons of media now. Even if you "own" something digitally, companies can zap it from your library.
