This thing gives me serious 1984 vibes. I hadn't read the book when I first heard of this, but I now realize the name is pretty much and open play on the tellyscreens in the book. Reminds me of the black mirror episode where you have to pay to stop watching.

Since I didn't comment elsewhere on the thread, my plan of attack for now is usually older TVs (even just a few years old are still really good quality), even if they are smart but not ever connected. Apple TVs on each one, also buy the 2-3 year old version of this used for about $40-$50 not any more then I used to spend buying Roku sticks. Gives me a good enough balance for now, and before Apple haters pile on, yes it's not perfect, but there have been some studies showing these are some of the best behaved streaming devices. More importantly than what the streaming device is, I have the ability to chuck them and add a PC or whatever else without having to replace the actual TV.
