A company is not an inanimate object; it is a collection of people working towards a shared goal. A knife cannot be evil, but a company (or, if you wish to be pedantic, the people who make up the company) can be.
What would a knife manufacturer have to do to be considered evil?
make an AI-powered knife that wants to stab as many people as possible, then market and sell it to despotic regimes.
Make knives that can only be used to kill people and solicit/provide the knives to bad actors who you know will use the knives for the purpose they were developed for?
The manufacturer giving the knives out to government agencies explicitly so that they can stab civilians more efficiently
I mean, I kind of reject where this line of questioning is going; I consider most of Palantir's product line to be inherently unethical, so I reject the notion that they can be considered a simple tool manufacturer, like a knife manufacturer could be.
