It's like Gaben said, piracy is a service problem, not entirely a cost problem. The same 20 euro subscription would've gotten be 100x more movies and shows a few years ago, whereas now it's split to a million random services. Sometimes one season of a show is on 1 service, while the next one is on a different one. You also can't get 4K anywhere, every service has shit quality.
So why bother paying, when radarr lets me get 4k content of anything I'd ever want to watch, completely for free?
