"One weird trick" ads aren't targeted advertising, they're advertising based on psychological tricks. It's a whole different ballgame. Targeted advertising is based around "if we show ads relevant to the user's interests, the user is more likely to click them and buy stuff", which is a win all around. Ads based on psychological tricks is "can we trick the user into doing something that's harmful to them but beneficial to us?", which is of course not good for users. Conflating the two advertising techniques doesn't serve any purpose at all.
