"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, according to internal
records and interviews.
The special
arrangements are detailed in hundreds of pages of Facebook documents
obtained by The New York Times. The records, generated in 2017 by the
company’s internal system for tracking partnerships, 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."
