Him and his company is pure evil. Sadly some EU government do business with them (Germany, Denmark) whilst what should happen, if the world was sane, is EU wide sanctions on Palantir and life-time entry bans on all employees, and if any details of EU citizens are in their system, arrest and criminal prosecution if he ever sets foot in Schengen.
Would you mind elaborating on why you'd call Palantir 'evil' in particular? I wouldn't exactly hold the company up a a role model of good corporate citizenship, but I also wouldn't put them down as particularly more 'evil' than your average multinational. Say, on a level with -- to pull an example not-quite-entirely out of thin air -- Airbus.
