I have family members who are otherwise not worried about having to save money who are dropping netflix as soon as they get done binge watching their current show. Why? because they are paying for four people to use the account, and because of their new rules their parents aren't getting to use the account since they don't live in the same house.
I hate to break it to you netflix, but octagenarians who have no idea how modern technology works aren't going to understand how to setup an account, and they definitely aren't going to want to deal with having to call their children every week when they are asked for the "permission code" just to have the privelege of accessing what their children are already paying for.
On top of this, I'm sure their children don't want to have to deal with having to input this on a weekly (or however so often) schedule. It's a frustrating situation all around, and I have no idea why they thought it was a good idea.
