I’m a privacy advocate but I just can’t pass up the otherwise amazing value of some of the smart tvs that have been released in the last few years, the size you can get for an reasonable price is incredible and for the first time is actually suitable at the viewing distance most people view a tv at. The colour, contrast and brightness is fantastic.
Having said that I added this block list to my router https://github.com/mboutolleau/block-samsung-tv-telemetry You can add it to a pi hole or to your router of it supports black listed domains. Sadly I can’t confirm if this blocks all Samsung tv’s shit. You can also never connect it to the internet and use an apple tv or something over which you don’t have more control.
