It's not so much the ads that I object to it's the the dangers associated with building up this incredibly incredible like a camera on our shoulder watching everything we do watch every message we type every conversation we have. There are people who are anti-capitalism and are also anti-advertising that's fineit's an intellectually honest position that I can respect.
