For me, it's that I want a significant portion of a piracy set-up for things that I can't get at all (4k actual original Star Wars trilogy, certain shows with the original soundtrack rather than a worse replacement, some obscure pieces of media) or for things I consider likely to disappear any time (YouTube videos) so if I'm going to have it anyway, I may as well also use it to avoid the "where the hell can I watch this?" shuffle. I do also pay for several streaming services.
