> Don't give your "smart" TV internet access. It's that simple.
For the tech users yes, simple. But for the non-technical user it's not.
The ISP given router don't normally provide the options for such. Nor would my mother, father, brother, sister even know about the slightest about networking, isolating networks.
My parents got a Samsung TV. At Christmas, I turned off all the data collection features (and some abysmal AI face filter that was ruining the latest Knives Out film). It very annoyingly started prompting to reenable them regularly.
TV-free here for about 6 years. I'd recommend it. It takes some getting used to, but after acclimating, the presence of TVs has become annoying. I'm not sure why I'd want to lose myself for an hour or two to it when there's more fulfilling things in the world.
I can see where you're coming from with your "more fulfilling things" statement, but I disagree. After all, TV's don't spew noise they spew stories. I'm not gonna argue that all TV is fulfilling, but engaging with stories is one of the the things which separates us from animals and to me is one of the more fulfilling things in life.
This is an area I'm keeping an eye on - currently this 55" Gigabyte one is about as good as it gets, but it feels like it's straddling the line between monitor and TV, as it runs Android and supports CEC and eARC.
