Edit: I guess this post is free advertising for these shitters, so I will describe what I previously linked.
There is this TV you can get for free but it has a ads on screen constantly and it has a camera pointed at you to record your reactions to ads and to ensure you don’t cover up the ad portion of the screen.
What’s stopping me from buying a smart TV and never taking it online?
Been doing it with mine for 3 years mostly. Jack-in just long enough to update firmware and software then disconnect
