Facebook gave Spotify and Netflix intrusive access to the private messages of users who linked their accounts, a New York Times report reveals. Spotify and Netflix had the power to “read, write, and delete users’ private messages, and to see all participants on a thread—privileges that appeared to go beyond what the companies needed to integrate Facebook into their systems,” according to the Times. The report also claims that “Facebook allowed Microsoft’s Bing search engine to see the names of virtually all Facebook users’ friends without consent.” Facebook also reportedly “permitted Amazon to obtain users’ names and contact information through their friends, and it let Yahoo view streams of friends’ posts as recently as this summer, despite public statements that it had stopped that type of sharing years earlier,” according to The Times.

Facebook claims to have found no evidence of abuse by its partners. In a blog post titled “Let’s Clear Up a Few Things About Facebook’s Partners,” Konstantinos Papamiltiadis, Director of Developer Platforms and Programs at Facebook, wrote, “none of these partnerships or features gave companies access to information without people’s permission.” In reply to the question “Did partners get access to messages?”, Papamiltiadis wrote, “Yes. But people had to explicitly sign in to Facebook first to use a partner’s messaging feature. Take Spotify for example. After signing in to your Facebook account in Spotify’s desktop app, you could then send and receive messages without ever leaving the app. Our API provided partners with access to the person’s messages in order to power this type of feature.”

Spotify were “unaware of the broad powers Facebook had granted them,” a representative told The Times. The music streaming company still lets users share music through Facebook Messenger and has access to the messages of more than 70 million users a month. Netflix US tweeted, “Netflix never asked for, or accessed, anyone’s private messages. We’re not the type to slide into your DMs.”

In their research, Times reporters studied hundreds of pages of internal Facebook documents and interviewed more than 60 people, including former Facebook employees and corporate partners, former government officials and privacy advocates. Read the full report.
