Facebook's outgoing security chief, Alex Stamos, sent a telling memo in March — reported by Buzzfeed News — calling for the company to "intentionally not collect data where possible, and to keep it only as long as we are using it to serve people."

The comments, first circulated internally months ago, shed new light on the personal reflections of the company's top security executive amid widespread privacy failings. The memo came just days after a pair of news reports revealed improper access to sensitive user information by research firm Cambridge Analytica — a revelation that kicked off a firestorm of international probes, policy changes and corporate soul-searching.
