My bet would be that the satisfying condition is disjunctive: either you're watching from an IP range that Netflix trusts, or you're watching from a device that Netflix trusts because it was fingerprinted and used regularly from that IP range.
What you can't do is give your password to someone outside your household and have them watch Netflix from their house whenever they want. Which, I mean, obviously that was never really OK.
> So you're saying if I have a non-share enabled tier, I can't invite people over to netflix and chill?
Curious, how did you extract that from the above? Inviting people over to watch with you isn’t sharing your account, nor is it watching from outside your household.
Sometimes different people in the same household want to watch different things at the same time.
And they still can.
If that's not what you're saying, then if I don't need sharing for use in the home, then what purpose does the share tier serve if I can't share it?
