If you shared data with Facebook over the past few years, there's a high chance Facebook handed it to Microsoft, Amazon, Spotify, or any of the other 150 companies that benefited from extensive data-sharing deals with the social media giant, The New York Times reports.
Internal Facebook records provide a more detailed look at data-sharing practices intended to help Facebook and its partners at the expense of users' privacy. For example, Facebook let Microsoft's Bing search engine view the names of "virtually all Facebook users' friends without consent," the report states. Netflix and Spotify could read account holders' private messages.
Documents show the partnerships primarily benefited tech businesses but were also done with online retailers, entertainment sites, automakers, and media outlets, all of which had applications seeking data of hundreds of millions of people a month. The oldest deals were done in 2010; all were still active in 2017, and some continue to be in effect this year.
Facebook says it's fading many of these partnerships and there is no evidence of data abuse by partner companies. It did admit to managing some deals poorly and letting companies continue accessing users' data after they had disabled application features that needed it.
The findings have prompted inquiries about an agreement Facebook made with the Federal Trade Commission in 2011. As part of the deal, Facebook was prohibited from sharing user data without permission. Steve Satterfield, director of privacy and public policy at Facebook, said to the Times that none of the company's deals dishonored the agreement or users' privacy.
Facebook holds that it was not required to obtain user consent as part of these data-sharing deals because it considers partner organizations "extensions of itself." Data privacy experts argue against this, and FTC employees say Facebook's partnerships broke their 2011 deal.

Facebook has since responded to the article. In a blog post published Dec. 18, Konstantinos Papamiltiadis, director of developer platforms and programs, explains how there were two purposes to granting major tech companies access to user data: to help people access Facebook accounts and features on outside devices and platforms, and to build "more social experiences" – for example, to view recommendations from Facebook friends on Pandora and Spotify.
People want to use Facebook features on devices and products the company doesn't support, he says. Integration partnerships with Amazon, Apple, Microsoft, and Yahoo aim to enable use of Facebook features across services. However, as former Facebook CISO Alex Stamos points out, there's a big difference between integration partnerships and sending secret data.
The former can be good: allowing for third-party clients, he says, is a positive move among dominant tech platforms. As an example, he points to Gmail: Limiting usage of Gmail to Android would be wrong. However, integrations that permit the transfer of illicit data to other companies' servers "really is wrong." Stamos calls for Facebook to build a table listing partner companies, the type of integration used, which data was accessible, steps needed to activate integration, and if/when the integration was shut down.
