The departures of Brian Acton and Jan Koum, the creators of WhatsApp, from Facebook followed disagreements over how to squeeze more revenue out of the messaging platform using user data — costing them about $1.3 billion, the WSJ's Kirsten Grind and Deepa Seetharaman scoop.

Why it matters: The disagreement stems from WhatsApp's hesitance to monetize using targeted ads — Acton and Koum have notably advocated for user privacy — as Facebook attempts to leverage the service's vast user base to justify its $22 billion acquisition in 2014.

Facebook COO Sheryl Sandberg told NBC's Savannah Guthrie that she expects Facebook will discover additional breaches in personal information when conducting audits of other third-party data providers, prompted by Cambrdige Analytica's misuse.

QuoteI’m not going to sit here and say that we’re not going to find more because we are.
— Sheryl Sandberg
