As much as I love bashing Google over privacy. And as highly probable as I believe the sort of glitch described is likely to occur, two things make me skeptical of this story.
A) That of all the random ways that a bug like this could manifest itself, it happened with a tech journalist on the receiving end.
B) That the author spoke with a live human Googler over a customer service issue in regard to a free service.
The real story here is B not A.
