Surely this is a non-issue if you don’t connect the TV itself to the internet?
Occasionally the out-of-the-box firmware on TVs can perform poorly on certain input modes, so it's nice to have an option to get the latest patches without opening yourself up to tracking and ads.
That said, the idea of a TV needing patches is thoroughly unappealing.
Also... what if they put a 5G SIM card inside the telly? Now that would suck.
