According to a report out of the New York Times yesterday, Facebook founder and chief executive Mark Zuckerberg ordered the company's high-level managers to switch to Android phones earlier this year. It's not clear if the order was ever enforced, or to what degree, but it apparently came on the heels of an MSNBC interview in which Tim Cook openly criticized Facebook's data collection and privacy policies in the wake of the Cambridge Analytica scandal and associated congressional hearings.

Cook's remarks apparently so upset Zuckerberg that he issued the Android phone directive - though, as The Verge points out, it seems unlikely that it worked (at least very well):

[W]e checked Twitter activity from several Facebook executives, including blockchain lead David Marcus and VP of AR and VR Andrew “Boz” Bosworth, all of whom are still shown to be using iPhones.
