Set up an openvpn/wireguard server at a "home" with bandwith, and have family/friends route their Roku/streaming device route through a router with openvpn/wireguard client back to the same "home" .
I expected that would be the move a lot of people would go but Netflix actually saw a net gain with what was thought to be an unpopular move. This is actually a really fascinating potential case study on piracy where you'd think it would lead to lost customers, but despite driving some away it actually increased.
Apparently it only saw a gain in subscriptions in countries where the price of Netflix is really low, so there's more factors at work in this case I think.
