The implication you'd have to pay to not have your wallpaper be made of ads is by far the most depressing part of this video.

Reminds me of this episode of Black Mirror (https://en.wikipedia.org/wiki/Fifteen_Million_Merits) that takes place in the future. In your room there are ads everywhere, and if you're not looking it stops and yells at you. To not see them you have to pay money.
