They could let you share your login with your family members that don’t live in the same house for a start, rather than making them create their own account having to pay $8 (or whatever it is in your country) per family household on my account.
As that person said, it should be like Plex - I pay for access and then I can share it with family without an extra charge. Netflix is now costing me like $50 a month just so myself and some of my family members can watch it. We probably won’t be subscribed for much longer, and will just rely on my Plex library.
