Just a couple of days ago I canceled my netflix subscription because of the user-hostile behavior of their roku app. Just clicking a show to read a more detailed description or get a list of actors in it would cause it to play automatically. Hit back, then select it again, it autoplays again. It's impossible to browse the catalog and add shows to my queue. Their support channel is useless, they just say they'll pass the suggestion on. There are threads on reddit and the roku forums with many people complaining about the same thing. Netflix also had a blog post about this "new feature" but after they got hundreds and hundreds of complaints they just turned off commenting and deleted all the existing comments. I know it's only $8/month but I'm not interested in giving any more money to these people. And we've been subscribers almost since the beginning.
It's nice that I could cancel online without calling in to support (a lot of online services don't let you cancel online). But it's telling that there was no survey asking why I canceled.
