Here's his thinking:
1. He's white and lives in a blue state. Doesn't affect him. Oh, and money. 2. The attention on Palantir and their customers makes his stock and options go up. He's happy, because money. 3. His GOP-worshipping parents get to brag to their GOP-worshipping friends that their son is helping God's Gift to Humanity - Donald Trump. And making bank while doing it. 4. He believes that Palantir is doing good work, and that's the end of it. He believes himself to be a genuinely good guy, so if he's doing something, it must be good.
