SAN FRANCISCO: Facebook Inc's chief product officer and one of its earliest employees, Chris Cox, said on March 14 he is leaving the company just days after chief executive Mark Zuckerberg revealed a plan to transform the world's biggest social network into an encryption-focused messaging company.
Cox, the 36-year-old Zuckerberg lieutenant who would have managed the CEO's vision to bring Facebook, Instagram and WhatsApp closer together, said in a blog post that his departure came "with great sadness." He had left a graduate programme at Stanford University to join Facebook in 2005 as a software engineer and helped developed its original news feed feature.
