There is a wide range of moral and practical opinions between the statement “all weapons are evil” and “global corporations ought not to develop autonomous weapons”.
Palantir exists, this would just be competition. It's not like Google is the only company capable of creating autonomous weapons so if they abstain the world is saved. They just want a piece of the pie. The problem is the pie comes with dead babies, but if you forget that part it's alright.
Palantir provides combat management system in Ukraine. That system collect and analyzes intelligence, including drone video streams, and identifies targets. Right now people are still in the loop though that is naturally would go away in the near future I think.
