Sheryl Sandberg: Facebook business chief leans out of spotlight in scandal

As Facebook faces scrutiny over data harvesting, the Lean In author and architect of the company's controversial business model has kept a low profile

In the wake of the Cambridge Analytica data harvesting scandal, there has been a glaring lack of leadership from Facebook. Almost five days of silence passed before its CEO, Mark Zuckerberg, faced the public with a post to his Facebook profile and a series of well-rehearsed interviews with handpicked media outlets.

As the public bayed "Where's Mark?", his right-hand woman, Sheryl Sandberg, has avoided much of the scrutiny, despite the fact that she is the architect of Facebook's data-centric advertising business and a highly skilled communicator.
