Defense of ad-tracking: increasing value for all parties by making ads more relevant and helping to keep services free. The only significant downside in my opinion is the possibility of data breaches giving the information to identity thieves etc. Otherwise I have no reason to be upset that some computers have determined, without any human involved, that I might be more likely to click on a Cheerios ad than a bicycle ad.
