Not sure about the US experience, but here in Australia there are no dumb TVs for sale in our retail electronics stores. Every TV comes with some sort of "smart" OS.
It's the same way in the US. That's why they were saying to just buy any TV (which will almost certainly be a smart TV), then just treat it like a dumb TV by not connecting it to the internet.
I was able to disable a bunch of stuff on my LG so I never actually see the WebOS interface anymore.
