I don’t understand how this happens. When they added this feature, it walks you through what is shared and who it is shared with. I made all my shit private. I mean, I’m annoyed the default was to share it all, but it’s not like the first notification of this feature was the email about watch history.
It forces you to review the share settings when you log in for the first time. I just encountered it on my Wife’s account. It’s not like they just sent an email saying “check your settings.” Again, I get the frustration with opt-out, I’m annoyed, too. However, people are definitely overreacting.
