When it comes to privacy violations in the digital age, this is so far down the list of concerns that I don't understand why we're talking about it. Probably just because some politicians in (I believe it was) Germany misunderstood what it is and took legal action against Google.

Facebook / other social networks, poorly secured databases, warrantless GPS tracking (in the U.S.), cell phone data being stored; these are all orders of magnitude more worrying and more likely to cause harm.
