I disagree. Many Palantir FDEs work on morally benign or even positive projects, for example helping hospitals during COVID. (Of course, many also do unethical work).
At Meta, almost everyone is contributing to unethical ends.
Engineer building Panzers is better then SS medic. No doubt there.
It is in fact better to be employed arms manufacturer then be member of SS - regardless of which position they put you in. You knew this is fascist organization as you was entering it and that everything you will do is to advance those goals.
I don’t know if the distinction holds. The philosophical base of where you work goes is the same: fuelling the Nazi war machine. Building a machine that kills thousands isn’t that distinct from healing a soldier that kills dozens. Meh.
SS medic would be also personally actively working on genocide. SS were selected elite soldiers, volunteerly there, ideologically commited to the cause and willing to take hightened risks.
SS medic joined because he was commited nazi. You can be arms engineer without being commited nazi or commited toward genocide. With SS, nope, regardless of position they assigned you to, you have to be confident fundamentalist to join in the first place.
As bad as Meta products are for society, I'd say Palantir is far more shameful to work for.
