The difference being not investing in something for ideological reasons won’t jeopardise your assets; whereas YOLOing your 401k on Palantir because “AI surveillance capitalism is dope lol” is potentially risking significant portions of your future.

Can’t people just retweet Karp on X if they want to “support Palantir ideologically”?

This is GME all over again.

Depends how you do it (I wouldn't put everything in one company no matter how much I liked them), but having money to invest does represent some power over the world so I understand people exercising it (though not why someone would choose Palantir).

GME is not the same thing: while I think there are some true believers in the company itself (and this is part of what drove the initial interest in it), for the most part interest in modern meme stocks is driven by the polar opposite: a kind of financial nihilism that believes hype and gambling on popularity is the only thing left in the public stock market, and they're basically just trying to ride the wave of a crowdsourced pump-and-dump and fleece others via selling to greater fools (and/or creating a cult around a mythical short-squeeze that is reaching ever more fanciful heights).
