Palantir is a data and ml platform. They don’t create point solutions for people. The solutions created are owned by the people contracting Palantir. If you hate on Palantir - you can hate on pretty much all industry in the west - oil and gas for supplying fuel, farmers for supplying food, consulting companies for consulting for the government, general population for paying taxes, etc.
This entire thing is just political showboating. I mean feel free to not buy food and fuel.
The parent poster's example was more apt with US Steel.
Palantir on the otherhand is a well known defense contractor and its stock price is arguably propped up by the US Department of Defen -- I mean WAR -- having an infinite budget.
Don't be licking Thiel and Karp's boots.
If these companies were breaking laws against big people (facilitating investment fraud, payment processing for terrorists) nobody would consider these methods of deflection for a second - it's only because the laws are being broken to hurt small people that the concept of aiding and abetting or acting as a willing accomplice is considered not relevant.
