Spotify's convenience killed the mp3, and Netflix is hyper convenient compared to most piracy. No one (to a rounding error, but let's say no one) is _really_ interested in file organizing, bitrates, buffering, whether a show disappears in 5 years etc. Everyone (again, to a rounding error) just wants to watch that latest season of that latest show and then forget it.
What's now making old-school piracy return is that while Netflix is convenient, having 7 streaming services is really _inconvenient_. Not to mention expensive. But the inconvenience is horrible.
I wish just 1-3 of the large streaming services would cooperate on some standard which lets me see and manage all my content in one place. Then devices could natively support browsing that "rss for streaming" instead of having N different services. Once a few do, the pressure on others to join the standard would increase.
