If they drill too deep they'd need to face very uncomfortable questions about other platforms too, e.g Palantir (Thiel was right there lurking ;)). Facebook is the Internet in many countries (making them less resilient and even more prone to meddling than the US). And so looking at it from the IC perspective FB is too big to fail:
- Remember Palantir worked with CA on the Facebook data it acquired: https://news.ycombinator.com/item?id=16690721
- Remember how confident in May 2016 Thiel was of a Trump presidency and when he openly started endorsing Trump? Was he operating with more knowledge than available to the general public: http://fortune.com/2016/05/10/peter-thiel-trump-delegate/
- His $1.25 million donation in October 2016 seems even more interesting now: https://www.nytimes.com/2016/10/16/technology/peter-thiel-do...

Oh and Palantir enables Immigration Agents to Access Information From the CIA: https://news.ycombinator.com/item?id=13895827
