Doesn't even discuss open-source when a key point its making is "tech is built on the backs of others".

>Anti-intellectualism is a profound skepticism or hostility toward science, higher education, and critical thought, often viewing intellectuals as detached elites . Driven by populist politics, religious dogma, and economic anxiety, it manifests as rejection of evidence and scientific consensus. It undermines democratic decision-making by prioritizing emotional narratives over expert analysis

I would say that there is another possibility to this. Experts and Expert opinions are susceptible to the same problem of social media echo-chambers[0].

Where new ideas and thought tend to be rejected because experts tend to rely too strongly in positions established over the course of a carrier.

So the concept of anti-intellectualism is not solely based on emotional responses. But also based on this concept of creating too much absolute certainty about a situation that doesn't always exist. People have a tendency to reject scientific basis of some information because of this echo-chamber as this dilemma tends to ignore other factors that are not well known. Also scientific pursuits have the possibility of being game by bad actors.
