Unfortunately the dirty secret of ad targeting algorithms is that they don't actually work very well. Computers aren't good at understanding context. It's a hard problem. Google is better at it then most and, well, you've seen AdSense. It's just OK. Both consumers and advertisers are mostly aligned in that they want relevant ads. The idea that taking away information about the user is going to somehow make the ads better seems like a stretch.
