Good morning.



Here’s what you need to know:

Facebook gave data to device makers

• The social media giant shared vast amounts of its users’ personal information with at least 60 companies — including Amazon, Apple, BlackBerry, Microsoft and Samsung — over the last decade.

The scope of the partnerships, most of which remain in effect, had not been previously reported, and they add to concerns about Facebook’s privacy protections.

The company said this year that developers had been cut off from the kind of access that had been exploited by the political consulting firm Cambridge Analytica. But Facebook did not disclose that makers of cellphones, tablets and other hardware were exempt from such restrictions.

• Facebook defended the data sharing as consistent with its privacy policies, a 2011 agreement with the Federal Trade Commission and the company’s pledges to users. They said they knew of no cases where the information had been misused.
