Grateful you taught me encryption: FB CEO to WhatsApp CEO
After WhatsApp CEO Jan Koum announced his departure from parent company Facebook, Mark Zuckerberg said, "I'm grateful...for everything you've taught me, including about encryption and its ability to take power from centralized systems." Zuckerberg added that he will miss working closely with Koum. Koum's announcement came after a report claimed that he would leave over data privacy disagreements.
