Don't buy a TV, buy a screen and connect it to your own media source. Preferably offline media. You can be a lot more deliberate about the content you consume and there won't be tracking (though there might still be ads in the media).
Anyone that researches can get a TV without ads for hundreds of dollars.
I don't buy anything from Samsung, it sounds like a user issue. Samsung is notorious for being awful.
Price != performance
I have a feeling that's about 95+% of consumers.
