The opprobrium over Facebook’s data privacy practices continues. This time, the New York Times reports Facebook has apparently shared an inappropriate amount of user information with device manufacturers, such as Apple, Samsung, and Amazon.

The details: According to the NYT, Facebook’s deals with hardware manufacturers predate the existence of the Facebook app. The company created APIs which would allow companies such as Apple or Blackberry to create Facebook-like features. To allow these features to function, the company agreed to share user data with the companies.
