Palantir employees should understand that they are not regular employees at a regular company. They are U.S. defense contractors at an U.S. defense company. Also Palantir customers should understand that by buying Palantir services/products they are doing business with U.S. defense company. I don't say that this is positive or negative, it just clarifies the relationships and it should set the expectations.
Boeing is a US defense contractor. Yet there are plenty of Boeing employees who can have a high expectation of ethics in their jobs. You may think you are being even handed and neutral in some way. If you are actually, find me that part of Palantir that's doing good.
