NBC said the emails, notes and other documents dated as far back as 2011 and were supposed to be kept out of the public eye pending the civil case in California.
They show, for example, how Amazon received special data access after purchasing advertising on Facebook, while an app called MessageMe was denied data after growing so large it became a competitor, NBC reported.
While acting out of self-motivation, Facebook planned to portray the moves as protective of user privacy, the documents showed.
The lawsuit was filed by a now defunct startup called Six4Three, which created a failed app called Pikinis.
Through the app users could find Facebook pictures of people in bathing suits, but in order to work, the app's software had to be able to access the data of Facebook users and their friends.
The suit accuses Facebook of abusing its power over user data, although most of the documents filed in the case have been sealed by a judge at Facebook's request.
