Facebook gave some companies more extensive access to users’ personal data than it has previously revealed, letting them read private messages or see the names of friends without consent, according to a New York Times report.

The newspaper on Wednesday detailed special arrangements between Facebook and companies such as Microsoft, Netflix and Spotify, in the latest revelations on how the social network shares user data.

Facebook shared data with more than 150 companies – not only tech businesses but automakers and media organizations – through apps on its platform even if users disabled sharing. Apps from many of these “integration partners” never even showed up in user application settings, with the company considering them an extension of its own network. The deals dated back as far as 2010 and were all active in 2017, with some still in effect this year.

Spotify, Netflix and the Royal Bank of Canada were able to read, write and delete Facebook users’ private messages, and to see everyone on a message thread. Spotify could look at messages of more than 70 million users a month and still lets users share music through Facebook Messenger, while Netflix and the Canadian bank have turned off features that incorporated message access.

Facebook let Microsoft’s Bing search engine see the names of “virtually all Facebook users’ friends without consent,” the paper said. Microsoft officials said Bing was using the data to build Facebook user profiles on Microsoft servers but the company has since deleted the data. Yahoo had the ability to show Facebook users’ news feeds, including posts by their friends, on its home page. The search company eliminated the feature in 2012, but still had access last year to data for nearly 100,000 people a month.
