However, the company defends its use of whitelists for specific partners like Lyft and Netflix, arguing "we changed our platform policies in 2014/15 to prevent apps from requesting permission to access friends' private information.in some situations, when necessary, we allowed developers to access a list of the users' friends" but not those friends' private data.
The documents were part of a California lawsuit filed by app developer Six4Three.
Internal emails at Facebook Inc., including those involving Chief Executive Officer Mark Zuckerberg, were published online by a committee of United Kingdom lawmakers investigating social media's role in the spread of fake news.
The release covers 250 pages including the MPs' summary and exhibits including emails from figures including Mark Zuckerberg and internal Facebook documents.
In terms of suffocating rivals, Mr Collins wrote: "The files show evidence of Facebook taking aggressive positions against apps, with the outcome that denying them access to data led to the failure of that business".
Facebook has refuted six specific areas, as laid out by the chair of the Digital, Culture, Media and Sport Committee, Damian Collins, in a recent blog post.
"We stand by the platform changes we made in 2015 to stop a person from sharing their friends' data with developers", the company said in a statement.
"We don't feel we have had straight answers from Facebook on these important issues, which is why we are releasing the documents", Collins said on Twitter. But the facts are clear: "we've never sold people's data". This includes that Facebook tried to hide from Android phone users that it was collecting data about their calls and texts in case it turned into a PR problem.
Collins also alleged that Facebook took aggressive positions against competitor apps by denying them access to any user data.
'To mitigate any bad PR, Facebook planned to make it as hard of possible for users to know that this was one of the underlying features of the upgrade of their app'.
In January 2013, Facebook VP Justin Osofsky emailed Zuckerberg about the now-defunct social media app Vine, suggesting that Facebook "shut down their friends API access".
A spokesman for Facebook was unable to immediately comment.
