Content feed: text and images you see when you look at your computer/phone

Outdoor billboards: text and images you see when you go outside and look around

I don't see what is dilutive about this comparison, seems about equal to me (except outdoor advertising is worse because you can't avoid it by not visiting certain websites). My broader point, I guess, is that the intended interpretation of the word "manipulation" seems to be restricted to "manipulation we disagree with".
