I don't understand how Palantir managed to sell their services outside of the US, given their deep ties to CIA, political positions and involment with US goverments.
Bribery.
Airbus is using Palantir services. The competition between Boeing and Airbus has often be brutal and dirty, and considered significant at the state level.
The fact that a company like Palantir be allowed to insert themselves in the software infrastructure of a critical company that is often working against the interest of the US seems very weird to me.
