https://en.wikipedia.org/wiki/Cooperative_principle

So historically, when someone accepted an interview yet refused to engage with any questions, or stay on topic, AND also was not interested in the smooth polish of PR-style transitions that would give an appearance of basic cooperation.. it was considered unhinged and obviously crazy behavior.

If interviewee acts clueless, drawling, or drooling then they could be pretty uncooperative and mostly get a pass because it's not very polite to point out stupidity. But for the big bonus crazy-points though, interviewee may opt in to escalation, becoming unabashedly and almost childishly combative, talking over each other, etc. Obviously all of these tactics are pretty normalized now though.

This is basically the goal. After the interviewee realizes the interviewer is hostile, they just double down on their talking points to signal to investors and ignore the intended audience of the interviewer. Mistake on the interviewers part honestly to publish it at that point IMO.
