Federal prosecutors are conducting a criminal investigation into data deals Facebook struck with some of the world’s largest technology companies, intensifying scrutiny of the social media giant’s business practices as it seeks to rebound from a year of scandal and setbacks. A grand jury in New York has subpoenaed records from at least two prominent makers of smartphones and other devices, apparently. Both companies had entered into partnerships with Facebook, gaining broad access to the personal information of hundreds of millions of its users.

For years, Facebook gave some of the world’s largest technology companies more intrusive access to users’ personal data than it has disclosed, effectively exempting those business partners from its usual privacy rules. Facebook's internal records provide the most complete picture yet of the social network’s data-sharing practices. They also underscore how personal data has become the most prized commodity of the digital age, traded on a vast scale by some of the most powerful companies in Silicon Valley and beyond.

Facebook failed to closely monitor device makers after granting them access to the personal data of hundreds of millions of people, according to a previously unreported disclosure to Congress. Facebook’s loose oversight of the partnerships was detected by the company’s government-approved privacy monitor in 2013. But it was never revealed to Facebook users, most of whom had not explicitly given the company permission to share their information. Details of those oversight practices were revealed in a letter Facebook sent in Oct 2018 to Senator Ron Wyden (D-OR).

Facebook has data-sharing partnerships with at least four Chinese electronics companies, including Huawei, a manufacturing giant that has a close relationship with China’s government. The agreements, which date to at least 2010, gave private access to some user data to Huawei, a telecommunications equipment company that has been flagged by American intelligence officials as a national security threat, as well as to Lenovo, Oppo and TCL.

As Facebook sought to become the world’s dominant social media service, it struck agreements allowing phone and other device makers access to vast amounts of its users’ personal information. Facebook has reached data-sharing partnerships with at least 60 device makers — including Apple, Amazon, BlackBerry, Microsoft and Samsung — over the last decade, starting before Facebook apps were widely available on smartphones, company officials said.
