I agree that buying "dumb" TVs is preferable, but they're often hard to find if you're looking for high-end features.

To quickly include the comments which often come up in similar threads -

There are some TVs you can find at BestBuy without smart features, but they're usually not 4K.

In many cases you can use a "smart" tv, and avoid putting it on your local wifi. Some TVs reportedly require internet access to work at all.

In other cases people have said that the device jumped on a neighbors open wifi without prompting.

People often say that including these "smart" features makes a TV cheaper for a manufacturer, since they can then sell your viewing data.

It's true, the last TV I bought was a dumb 55" that I got for maybe $480. It was hard to find though, and it was a model a few years old at the time. Incidentally I got it from Best Buy. But absolutely, try to find a new TV with top end display tech without smart features? Nigh impossible, unless you pony up for a commercial display.
