> “We love people sharing Netflix whether they’re two people on a couch or 10 people on a couch,,” Hastings said. “That’s a positive thing, not a negative thing.”
> To illustrate this example, he spoke of how a parent may share their login with their child. And when that child grows up, they will usually subscribe to Netflix, too.
> “As kids move on in their life, they like to have control of their life, and as they have an income, we see them separately subscribe,” Hastings told reporters at CES. “It really hasn’t been a problem.”
> While Hastings didn’t directly address how he feels about non-family members sharing their credentials – such as in the case where friends or roommates may split an account
From [1], at least, it doesn't appear that he ever intended password-sharing among multiple households to be a thing?
Even in [0] (which I would consider a poor reference since it's about the crackdown and therefore starts out trying to prove a point...), I think there is a fairly reasonable interpretation of "Love is sharing a password" that doesn't include 3+ households sharing an account.
