The approach I’ve taken is to just keep my TV off the internet (never join a WiFi network) and make it smart via an Apple TV, which I personally believe to have the strongest privacy protection of any smart TV device. Another bonus is my TV UI hasn’t changed despite changing and upgrading TV brands.
It's 1/4 the area, minus all features, AND the same price!? 8-/
It's a great option, for dell shareholders...
