I don't care if advertisers know more about until they can actually identify who I am (name and contact info) and start calling me, sending me emails, and mailing me directly.
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.
If you see a random ad for a company on Google, click on it and then supply your email. Then they would know a lot more about than just your email. They would know every demographic filter they used to create that ad. That could be quite specific.
True, if the company only created one campaign and it was pretty specific, then yes, they could tie my signup to the campaign information. I'm not terribly concerned about this yet.
Let's say there's a SASS service you can tie into that has a massive database of browser fingerprint activity. Potentially you could get quite a significant amount of browsing history once enough websites are using the service. You can tie this to an email address etc. when a site requests a signup.
