Agreed. It's what brought me back to piracy. I can pay one or two subscriptions max and happy to do it, but if the content I'm looking for is not there guess where I go to? And I suppose that many others do the same. In addition, many streaming websites have content that disappear for no apparent reason, or have the content only in some countries etc.
Streaming has reduced the need for piracy a lot, and that's probably a good thing, but it hasn't made it completely obsolete, because of silly models that media companies still enforce.
