Look, if the corporations that make the tv's decide that listening isn't enough, they need to watch us as well. You buy the tv. There is a camera feature that is not mentioned on the box anywhere. You get the tv home, set it up, but unless you sign the EULA, the tv won't work. At all. So you sign the EULA to watch tv or play a game and you say 'I'll turn that feature off later'. But you can't turn it off.
And of course, its only so they can serve your advertisements more accurately. I mean if I wear crocs, why not push croc ads at me incessantly? If I wear a t-shirt or hat with any printing on it, sell me an ad for the product.
I think this is where we are going.
