This is the third story now that William Alden has written about Palantir that appear to be based on internal documents[0]
His profile of the company a month ago opened with:
> A trove of internal documents and insider interviews has pulled back the curtain on one of Silicon Valley’s most secretive and highly valued companies, Palantir Technologies.
There isn't much public interest in large parts of the profile nor the follow-up stories, so it has a feeling of a disgruntled employee. A really difficult class of threat to defend against and stop, but each additional story and leak provides a few more bits of data that can narrow down the suspect pool.
I really hope the leaker and journalist in this case know what they're getting themselves into - because based on the pentest report the infosec team at Palantir appear capable of tracking the leak down.
