I do understand the media attack on Palantir for two reasons.
1) The products are used with programs and activities that people and groups are opposed to.
2) Thiel is not liked by half of the country because of his corporate status/ history and his very open support for Trump in 2016.
Responding to #1, we can make the same argument against Microsoft if a SOF or ICE mission is briefed on PowerPoint, then MS is guilty of caging children or raiding a known terrorists residence. Or Adobe since the mission was turned into a PDF and emailed to others on a secure internet protocol. Or Dell because that was the hardware platform used by that agency. Long story short, this use of Palantir by politicians and media is just political spin.
For #2, I can't say much other than it seems unwise, in my corporate opinion, to alienate half of the country by placing a "Pres CANDIDATE - VP CANDIDATE 2020" sign in your corporate lawn.
Fortunately, our contracting regulations can prevent that from being the reason in US Gov contract work. Look at Elon Musk, he sued the US Gov (NASA) because SpaceX was not included in contract proposals. Everyone thought he was insane to sue the company he wanted to do business with. But he won and is now NASA's exclusive #NAStrAnaut and cargo delivery vehicle. Theil did the same thing with the US Army when Palantir was not allowed to submit proposal for the use of the system against the current contract with the DCGS-A program, and won. PLTR has not beat out the behemoth, bloated, money-gulping DCGS program, but won the lawsuit. Now provides a tactical platform in use right now. This is on top of their other SOCOM and USMC contracts.
