This. Parents bought LG OLED TV. It is absolutely lovely, has super nice picture. (not an ad!:D) I insisted they never connect it to network. Probably it would be usable on network cut off from internet, but there is high probability of some mistake. I wasnt sure what happens if it got out for just a tiny bit so decision was clear. We've seen zero ads there (except the standard-ads-iterrupted-by-actual-programming).
