We share all our streaming services and so far nothing has happened because we don't use smart televisions but only dumb monitors connected to PC/laptop. They can't figure us out. I don't think I will ever use a tv again, first because we do not watch live tv anymore, second because smart TVs spy on us and on top try to put ads on and other shite. A mini PC in the living room looks cute, can play anything including local data and they can't tell if accounts are shared.
