I'm trying to figure out what you're suggesting here. That we should ban advertising? That untargeted advertising is somehow socially better than targeted advertising?

Practically every commercial interaction (and most social interactions) are "manipulation" of some sort. At the moment we're trying to manipulate each other into adopting the other person's perspective. I don't understand what you find insidious about sales pitches; I'm sure they've been with us almost as long as prostitution.
