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.
You can mute, but the ad will pause until you unmute.
Which makes the button almost completely useless.
That would mean the “unintrusive ad screen” isn’t unintrusive, if the ads shown in it also play sound.
