we announced in late 2018 the wind down and discontinuation of many of the integrations we built with partners. Recently, a third party alerted us to a bug, which led us to investigate and find that, unfortunately, our codebase had enabled continued data access for some of these partners. Although we have not found evidence that any data was used in violation of our policies, we are restricting their access today.
Of the dozen partners that we identified as continuing to access data, only two, Microsoft and Sony, continued to access limited types of friends data. This was old code supporting known experiences for people, such as being able to use Facebook on PlayStation or to sync their friends' contact information with another service. (Updated on July 24, 2019 at 9:50AM PT to correct the Playstation example.) Based on our previous commitments, we are ending these partners' access to friend data immediately. This was our mistake, and we are correcting it.
