Most media piracy is a direct result of it being somewhere between inconvenient and impossible to consume that media legally. See, for example, the tremendous drop in music piracy resulting from various music streaming purchases and Apple's popularization of direct track purchases before that.

Movies and shows, by comparison, are not just absurdly fragmented* but often literally unavailable not long after release for bizarre tax dodge purposes.

IME the cost savings of having a good piracy set-up (good = won't lose a ton of stuff on a single disk failure; streams well to your viewing devices in a way that normal people and visitors in your house can use without help) isn't even that large. I definitely wouldn't bother if I didn't have to have it to have (convenient) access to quite a bit of stuff I can't get any other way.

But once that's set up... adding more to it adds basically zero more marginal work, and when everything's in one interface the UX is crazy-better than any legitimate option on the market. So, may as well.
