Here in the UK you can buy a normal TV without any tracking. Its expensive (200-250+ pounds vs 120-150 pounds for normal spyware)
But it doesnt matter. Normal people dont care about this shit, only the Hacker News types. My wife put her foot down when I said we should get dumb TV, and we ended up getting a Samsung even though I wanted to avoid Korean companies (as they have worst privacy features), mainly because it was in our budget and available
Its feasible up to 32" to use a computer monitor and android box, but over that monitors seem to be up to 3x the price for equivalent specs versus televisions.
A 65" 4K TCL is about $400-500. Cheapest equivalent monitor is over $2k that I can find.
