Earlier quoted context omitted.
You can share your account, with other people at your same physical location. You can't share your account with people who are going to be primarily watching Netflix from a different physical location than your own. Does not seem unfair, IMO.
So you're saying if I have a non-share enabled tier, I can't invite people over to netflix and chill? 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?
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.
