i've seen this happen with people that have had much much smaller financial success in the industry..or even ones that haven't had any at all. you are either naturally inclined to identify with the culture or you trick yourselves into it so that you may belong.
<insert paragraph about social desire to be connected and how we construct an image of ourselves through others>
the culture of SV today is an amalgamation of Taylorist ideas, Randian objectivism, Utilitarianism etc etc. there is a lot of social capital to be earned by embodying the values of these currents. DOGE is a quintessential representation of this. it is not surprising at all that author had such a visceral reaction to it.
its important to emphasize that there have been very successful companies that have gone against the current (ie Apple), with an emphasis on craftsmanship, obsession with the process, taste-driven vs data-driven decisions and appreciation for things that are outside of profit maximization.
