But it does, because of the effect just mentioned. 99.999% of people can take the path of least resistance while the 1 in 100,000 exception bears all of the friction for all of them.
Perhaps though the real friction is not exactly technical but that the piracy sites don't have the same attention-capturing "feed" or recommendation mechanisms set up. Just the friction of having to make choices.
There are still entire websites dedicated for TV shows and music (and after you have looked at them once, they show up on Android feed), Facebook and Twitter feeds, etc. And I guess everyone agrees that Netflix recommendations are not that great.
