I tried to find the article, but of course it is lost to the anals of the internet. (Yes, I know what I said). I saw an article a couple of years ago about how there was a push in China that would use the built-in cameras in smart TVs to watch how many eyes were looking at the screen during rented features and charge extra if there were more than some small threshold of people watching it. I think 3 people were allowed for a single rental price and it would be charged again if more than that watched.

This is likely coming for us. Also… Yo ho ho.
