We just bought a vizio to replace one that broke. Once you skip the setup process, all you need to do is remove the solder from the 'home' button on the remote or whatever it is and you'll never see their pop up crap again.

I get why people like this, though. It takes all of your accounts and puts them in one place. Honestly, if I could run Plex and my own media through it, it would be tempting to just block it from dialing out and get rid of my Nvidia shield.
