I don't think your comparison is apt. Mudge isn't some loose cannon. He worked for the US government as a program manager for DARPA from 2010-2013, then for Google from 2013-2020. You think he looks "corporate" now, just look at his government portrait on his Wikipedia page from a decade ago.
Point being, Mudge is a very well respected cyber security professional, not some "hippy hacker" from years past. Which makes me even more willing to give his accusations weight, because this is not a case of someone who doesn't "get" corporate environments.
