Heh. That's what happened to me. Got a "smart" Vizio TV 4 years ago. It had a Skype + camera option. One night saw camera light come on when I wasn't using it. Quickly yanked that out. Then at some point the "apps" for Amazon stopped working for it. So that's when I disabled its networking plugged in a fire-stick and just using it as a dumb large screen for Netflix.
Actually that is an interesting niche to play in -- sell a high quality TV display but just with lots of USB and power ports in the back so people can plug in their favorite stream devices. It would be lighter and thinner as well. More power efficient.
Can even make a play on "this is secure, unlike other such devices". And of course the "you save by not paying for extra crap you don't want to use". Advertise that to a few sub-reddits which do xmbc, kodi development, cord cutters. Maybe get Costco on-board as well.
