In a counterfactual world where IBM did not sell them the equipment, the Nazis still would have figured out a way to mass murder people. The Japanese and Stalin and Mao did not have access to IBM tech, but they still mass murdered people.
The parent post from a former employee suggests that Palantir is in a similar position:
> They build a federated search engine with a simple UI to make it accessible to a non-technical audience. That’s it.
That's not a value proposition that is beyond the realms of possibility for other companies to develop. So why does Palantir appear to engage with more unethical projects that other companies if it's not by having a low ethical standard? (Obviously I can only comment on what is public knowledge.)
If the technology is not truly required by the unethical client, then you are doing a good, by taking their money and providing technology they don’t need. Money they give is money they can’t spend for other stuff that they truly need.
> In 1937 IBM's tabulating equipment enabled organizations to process huge amounts of data. Its clients included the U.S. Government, during its first effort to maintain the employment records for 26 million people pursuant to the Social Security Act, and Hitler's Third Reich, for the tracking of Jews and other persecuted groups, largely through the German subsidiary Dehomag. The social security-related business gave an 81% increase in revenue from 1935 to 1939.
