This is my take on things but happy to hear other views. Google (and Facebook) are advertising based so try thinking about it in terms of how well they know their users. The better they know their users, the more specifically they can target ads to them. For example, if I wanted to reach 20-somethings, who really like pizza and motorbikes, travel widely and currently reside on the west coast, FB can put ads in front…
I have to say that it sounds like an excellent reason to drop gmail and move away from google products. I don't _want_ advertisers to know more about me.
Since it's not in Google's or Facebook's best interest to allow a direct connection between their advertiser's and users (if they no longer act as the proxy, where's the money?) I'm not terribly worried about it.
I would like there to be more than just a vested interest in not revealing my identity though. Something legal ensuring they take it seriously would be nice. Like being able to sue them should they mistakenly expose my identity via some third party's clever fingerprinting etc. As long as I stay anonymous and protected (from big brother etc.) though I really don't care. I just think we need more assurances that we are indeed anonymous, gov included, which currently isn't the case.
