This was more or less my response as well. The 'academy as monolith of truth' is so 20th century. And, of course, disagreeing with Newton is very different that disagreeing with Freud. And we certainly aren't surprised that dupes got the Dunning Kruger.
But I worry about the impact of this line of thinking as we see it repeated in mainstream contexts. "Consensus as measure of truthiness" is incredibly problematic.
