I get this policy in theory but don't see how it works in practice in a modern life where you want some device that runs Netflix, YouTube, of similar to show on your TV. It can be the TV or an android box - but somewhere you end up trusting a third party and a software that may end up running other this party apps. The alternative is a local jellyfin server but that means you very likely have to break some laws to put content that the family wants to see on it. Personally I'd just not want any TV in my house, but convincing the family of that is not easy ;-)
