There's a variety of reasons, but many of us don't want any of the "smartness" and all of the stupidity that comes with "Smart TV's" these days, but don't really have comparable "dumb" options at similar or cheaper price points. The Telemetry (ACR), unremovable copilot app getting added to LG TV's, or all the Ad's Samsung are cramming into their "smart" garbage are three prime examples, but certainly not the only reasons I hate smart TV's (or really any device marketed as "smart") these days.

Most importantly though, can you even get non-smart TV's these days that aren't super budget items? To my knowledge that's pretty much not a thing anymore (yes there are presentation displays and large format monitors, but that gets into the weeds fast about feature/panel/spec differences, not to mention price differences)
