> So why are John's friends using the living room so frequently yet without having any contact with him?
Good question. I rent out a house with 100% capacity, and I haven't set foot in the house in the past year at all. It's managed remotely by me. There are living areas where people can hang out. This is also what John does.
> you ask us to imagine that the friends haven't given any permission. Permission for what exactly?
I have edited that part out and made things more concise, thanks for catching that. John records his living room and uses the data in order to sell products to the people who happen to be there. Later, people found out and have politely asked him to delete any video and audio involving them.
Side note: I feel John's implementation isn't important here, so I've intentionally left it out. Perhaps he earns a profit by having buyers and sellers meet, serendipitously, in his living room. For example, he may learn that Alice is a laptop seller and Bob is a laptop buyer. Assume John can influence the traffic in his living room for the sake of the gedanken.
