The view-state sync feature and all the social stuff is def opt-in though. Of course they made it super easy to do the opt-in, they want to push that feature, but I remember I did have to actively choose both of those things after the update.

Obviously I don’t really want my “friends” getting weekly emails about what I’m watching, but I don’t know — If I were self-hosting my own porn, maybe I’d take 5 extra seconds to read the screen that says stuff about sharing activity.
