"It is not clear that there was any user consent for this, nor how Facebook decided which companies should be whitelisted or not", the summary states.
The company also apparently collected data about app use by phone users - apparently without their knowledge - to determine who its biggest rivals were and which companies it should aim to acquire.
"As we've said many times, Six4Three - creators of the Pikinis app - cherrypicked these documents from years ago as part of a lawsuit to force Facebook to share information on friends of the app's users". It's suing Facebook over a change to the social network's privacy policies in 2015 that led Six4Three to shut down its app, Pikinis. He'd obtained the documents after compelling the founder of USA software company Six4Three to hand them over during a business trip to London. It includes emails between Mark Zuckerberg and his staff.
Facebook's thoughts about its competitors and potential rivals can also be seen in the internal emails, an approach which Collins labels "aggressive". "We don't feel we have had straight answers from Facebook on these important issues, which is why we are releasing the documents".
Damian Collins, a British Member of Parliament, released 250 pages of emails and findings on Wednesday that examine how Facebook treated user data amid its increasing dominance in the social media market from about 2012 to 2015.
"It is clear that increasing revenues from major app developers was one of the key drivers behind the Platform 3.0 changes at Facebook", Collins added. Facebook planned to make it as hard as possible for users to know that this was happening. "The documents Six4Three gathered for their baseless case are only part of the story and are presented in a way that is very misleading without additional context", a Facebook spokesperson said. "In some situations, when necessary, we allowed developers to access a list of the users' friends", the company said.
"Like any business, we had many internal conversations about the various ways we could build a sustainable business model for our platform", Facebook said.
Facebook's director of developer platforms and programs Konstantinos Papamiltiadis told AFP last week that the company "has never sold anyone's data".
The documents suggest robust internal discussions about linking data to revenue. "I think we leak info to developers, but I just can't think of any instances where that data has leaked from developer to developer and caused real issue for us", chief executive Mark Zuckerberg said in 2012, describing nearly exactly the kind of behaviour that would lead to the Cambridge Analytica scandal years later.
