Facebook's short-lived (but soon-to-be-re-enabled) experiment with sharing users' addresses and phone numbers with third parties did not impress certain politicians. Indeed, Representatives Barton and Markey, Co-Chairmen of the Congressional Privacy Caucus, were bothered enough to write to Mark Zuckerberg. In fairness to Facebook, the company only intended to share users' data with their permission. It was quick to back down in response to criticism, too. So a thought about political grandstanding might not be out of line.
