> The four screen plan has always, since it's inception, stated that is for four people who live in your household in the terms.
As I read it, this is the parent poster's point. An individual person is unlikely to use Netflix on two devices simultaneously, so a notional "four screen plan" that also charges per profile (as per the linked article) undermines itself.
The linked article doesn't say it charges per profile, and nor does the Netflix document.
It says the additional household subs get an extra profile for them, and that there will be facilities to transfer profiles. There's nothing indicating that the account won't still be able to have five profiles for people who live in the household, as is currently the case.
