Regardless of what you or I think of the policy, most major software companies (Google included) have clauses in your employment contract around how you represent the company in a real or percieved official capacity. This wasn't just some account persona; it was published as if it were an official open source product endorsed by Google (complete with branding). The author apparently didn't have permission or legal right to do so, and publicly violated their agreement.

Was the response short sighted? Up for debate. But unfortunately for the author, they have no real legal standing on this matter. Had it been their own repo, sans any branding, it would likely have been fine.
