You make an excellent and fair point about the use of Chrome, as well asYoutube and other popular Google-owned products. That certainly makes it far less than my pulled-out-of-my-ass 99% claim. :) It would be interesting to actually see the breakdown between Google's 1st party tracking (direct-from-Google) vs Google's 3rd party tracking (Tracking thanks to 3rd parties) >If Facebook is to blame more than the websites putting their like button on their websites I think the problem here is how Facebook sold the user data and/or used the data to target - as it allowed much more narrow demographic targeting than I think even Google provides. (I could be wrong on this, I've never actually USED either for ads - although I work for a company that does so I really should probably know this...)
