On Tuesday Facebook denied that companies like Microsoft, Amazon, Netflix, Spotify, and Yahoo were able to misuse Facebook users’ personal data. The internal documents describing the Facebook partnerships with other tech companies, reports on previously undisclosed aspects of business partnerships with companies including Apple, Amazon, Microsoft, Spotify, and Netflix.

Reports suggest Facebook allowed Microsoft’s search engine Bing to see the names of nearly all users’ friends without their consent. It lets Spotify, Netflix, and the Royal Bank of Canada read, write, and delete users’ private messages, and see participants on a thread. Moreover allowing Amazon to get users’ names and contact information through their friends, and also letting Yahoo view streams of friends’ posts despite publicly claiming it had stopped sharing such information a year ago, the report said. Collectively, applications made by these technology companies sought the data of hundreds of millions of people a month.

The records, produced in 2017 by the company’s internal documentation for tracking partnerships provides a complete picture of the social network’s data-sharing possibility. They also investigated that how personal data has become the most prized commodity of the digital age.

Facebook Partner companies acquired features and personal data to make their products more attractive. Once a user logged in and connected their Facebook profile with these accounts, these companies had access to that person’s private messages.

Facebook has been facing several issues of privacy scandals since its Cambridge Analytica that improperly used Facebook data to build tools that aided and accelerated President Donald Trump’s 2016 campaign successfully. Confessing that it had breached users’ trust, Facebook insisted that it had instituted stricter privacy protections long ago.

However, Facebook has found no clear evidence of abuse by its tech partners, a spokeswoman said. Some of the largest partners of the social networking giant including Amazon, Microsoft, and Yahoo exclaimed that they had used the data appropriately, but declined to discuss the sharing deals in detail. Facebook did say that it had mismanaged some of its partnerships, allowing certain companies’ access to continuing long after they had shut down the features that required the data.
