Your comments seem to underscore how Google controls the debate by defining the terms on privacy issues. You seem to be saying "Concerned about privacy? You could check up on Google by acting like one of its advertising customers.." which sort of highlights the parties Google is most interested in being transparent with (for completely understandable business reasons).

But of course in order to do that, you also have to have a login, cookie, etc. for a panel that Google controls, and that exposes only a tiny subset of the information it could most obviously and trivially correlate about user activities.

These just aren't really things people trying to visit wordpress sites should have to consider..
