It's not hard to find long posts of me calling the people in the Trump administration "profoundly stupid", with both my "tombert" alias and my real name [1]. I'm not that worried because if Palantir has any value they would also be able to tell that I'm deeply unambitious with these things, but it's still something that concerns me a bit.
[1] Not that hard to find but I do ask you do not post it here publicly.
