Cromwellian (while awesome, and someone who never fails to impress me with his writing) is not speaking for Google, or even other Googlers. He is speaking for himself. As is his right, I'd hope you'd agree, even if you (like many) would disagree with some of the things he writes.
(Edit: you changed the first sentence. Which reads better, thank you. Though I would actually still make the case it's far less contemptuous regarding privacy than you suggest. Worth reading deeply, since I think what he is saying is nuanced.)
