Bear in mind that Antenna (the source of this info) has no access to internal Netflix metrics, only to opt-in consumer information. We won’t really know what’s going on with Netflix’s numbers until their next quarterly report.

It’s a little buried in the account settings, but Netflix does allow account sharing for an additional fee (~$7?). I know families that went with this option so they could continue sharing their account with elderly parents, and college aged children.

I imagine that if a group of friends agreed to split the cost of an account + fees, they would end up paying less than having individual accounts.
