I don't carry a smartphone, I don't have a Facebook account, and I use NoScript, so I have a certain amount of privacy online; but there's not much expectation of privacy in public places. (Not zero, evidently -- Google blurs out faces on Street View, for example -- but not much.) And in this case, Google's not revealing personal data at all, they're finding and reporting industrial problems; their wide-ranging, unaccountable cyberstalking powers are very creepy, but this time they're being used for good.
