Zuckerberg Says Facebook to Emphasize 'Privacy-Focused Communications'

Facebook chief executive Mark Zuckerberg announced a sweeping reorientation toward privacy, explaining in a lengthy essay posted to his account that he would spend the coming years focusing the company’s distinct apps — WhatsApp, Instagram, Messenger, and Facebook — on content that is encrypted, meaning data is scrambled so that outsiders, and even Facebook, cannot read it. But the shift, which shows how the embattled company is positioning itself for an uncertain future marked by consumer distrust, declining growth on its core social network and ongoing fights with regulators around the world, could cause an upheaval in Facebook’s business model of mining people’s information to show them ads.
