I reached a point in my late 20s where I had enough money coming in and there were only a few streaming services where I decided to minimise my piracy if I could conveniently access something legally to make up for all the piracy I did as a teen. Seven years later and inflations huge, my pay hasn't kept pace and every tom, dick and Harry have their own service now. So it's been back to the high seas for me.
This dilution of content is really the issue. If Netflix still had the movies I want to watch, I'd just use it. Netflix is easier than piracy.
But Netflix doesn't ever have what I want to watch anymore. Now those movies are scattered across half a dozen other services that each cost $15/month. It's a pain to figure out what's streaming where and if it will cost me anything extra on top of my monthly dues. As Gabe Newell said, it's a service problem.
Piracy gets you more centralized access to more content for free. If you're behind a VPN or use a private tracker (or both) it's safe. So why spend all my money on Netflix and Hulu and Prime and Disney and Max and whatever else just to have a fifty/fifty chance that one of them might be streaming the movie I want to watch?
