Family accounts are inherently blurry. There are families where someone moves out (e.g. a teenager graduates) or lives outside the home (e.g. Grandma's in a nursing home). Some groups of friends get together, call themselves a family, and pitch in for an account. Some families spent the summer in a cabin. Some people are away from home for more than 2 weeks at a time (traveling through many destinations). IDK how they support multiple profiles in a way that's fair to everyone.

I will say that Netflix hasn't added much value to my life over the past years. Most of my watching has either been with other people (e.g. going to a friend/family member's house and casting from my account), or on an airplane. My parents and my brother have profiles on my account - we live apart, but we're still a family.

My main motivator for keeping my Netflix subscription is not interrupting my family members when they do want to watch something. If Netflix starts charging per "house" that you login from, I'm canceling my account.
