I'm usually very critical of and sensitive to any privacy issue. But the Google profile is a public profile, which is made abundantly clear on every occasion. This is what you see when creating the profile:

"Decide what the world sees when it searches for you. Create a public profile to display the information you care about and make it easy for visitors to get to know you. [...] Your profile will be visible to anyone on the web, and anyone with your email address can discover it."

I fear that this kind of completely spurious criticism discredits anyone who has real privacy concerns.
