Oops: Facebook caught planting anti-Google stories to press
First mistake : attacking Google, also known as the overlord of the internet (as far as the internet has one)
Second mistake : attacking a feature that was largely unknown. I just learned of its existence, thanks to this story ! 
Third mistake : getting caught
Fourth mistake : When you're Facebook, you should never ever complain that anything is a violation of privacy. It's like a fast-food company claiming something is low quality food and an insult to taste.
