Facebook Granted Data Access to Chinese Telecom Firms

Facebook allowed Chinese telecommunications firms to gain access to users’ data, the social-media giant said Tuesday. Among the firms granted such access was Huawei, about which U.S. intelligence officials have raised national-security concerns. Facebook told The New York Times that it would wind down its relationship with Huawei by the end of the week. Facebook also said the user data that was shared with Huawei stayed on Huawei devices themselves rather than the firm’s servers, and said the agreements were similar to those the company had with BlackBerry.
