My TV thinks it's January 1st 1970.

I've said it before on HN a long time ago but I'll repeat myself, I have about a thousand times more confidence that Sony and/or Microsoft will keep their PS5 and Xbox operating systems secure and not crapped up with stuff like this, than I do that random TV manufacturers will not result in a cybersecurity or privacy disaster.

Yeah, the PS and Xbox OSes show you ads, and they have telemetry. But both companies also have an extremely important core functional need of keeping them secure, because possible fuckery with the OS could result in game piracy/DRM bypasses and a direct threat to their revenue models.

Hope you don't have any open WiFi networks nearby. IMO it's better to put it on one of your networks and isolate it from the internet and other devices.

Pretty sure they can get internet through the HDMI cord from Roku or similar device

This is the best approach
