Careful, there is a lot of propaganda against Palantir because they stand against big tech, Silicon Valley, and its political agenda - which controls the majority of the media.

For example: The first story, it was later confirmed Palantir declined it, even the whistleblower admitted that they were just talking but never amounted to anything https://www.cnbc.com/2018/03/27/palantir-worked-with-cambrid...

I also encourage you to read in detail MiJente's report on ICE, I had to stop midway due to personal attacks on Thiel, nothing related to the business, it seemed like propaganda whitepaper.

There is no question how far big tech will go to brainwash the population with ads, as they profit from that business model and squash every opposition against them. Be very careful of what you read online, even in HN.
