WhatsApp founder and chief executive Jan Koum is leaving the company more than four years after it was bought by Facebook following what the Washington Post, which broke the story, describes as fights with the social giant over data privacy issues.

Why it matters: Koum's departure comes as Facebook faces scrutiny from users and regulators over its treatment of consumer data — and right before its F8 developer conference.
