Same here. I barely used Netflix and was only paying the bill because I shared the password with family members and didn't want to cut them off.

Once they started being weird about account sharing, there was no reason to keep paying the bill. I was on the top tier too, because they said you could play on 4 screens at once, and I figured it was fair to pay extra since I was sharing the account.

Nobody in my family complained so it's likely they weren't really using it either. So instead of a top-tier account being shared among a bunch of people that didn't really use it, they get nothing.
