Besides the fact that many TV manufactures are owned by Chinese government subsidiaries, it's simply not safe to connect a TV to the internet. Who's collecting and selling the data? Why are they taking screen captures and sending them off to who-knows-where? Your TV spies on you[1].

Instead, my TV stays offline and I use an Apple TV. At least I know they're not selling my data to advertisers, and the experience is quite good.
