I actually bought a Vizio TV years ago on the basis that it was sold with extremely unobtrusive software -- it had Chromecast support and a configuration/remote app you could put on your phone, but otherwise it did what you told it to do and stayed out of your way. They actually released a firmware upgrade six months or so later that added a crappy smart TV interface that has gotten increasingly crappy and intrusive over the years. It was infuriating. I had no way to opt out.
