I worked at the same company as the banned individual (Peter) some years ago. We were even on the same team for a time. Smart guy, but his caustic snark and condescension frankly overshadowed the technical and organizational impact of his work. I got a distinct sense of an unhealthy degree of hipster vanity for a lack of a better way of framing it. I have no axe to grind, but I'd have thought twice about hiring him for a team I was running (no place for toxicity in the workplace). To this specific incident here, I'm a bit taken aback by the level of immaturity documented in the writeup, as even this seems beneath what I observed from him in the workplace. Nevertheless, his poor attitude makes the episode seem plausible. A dose of humility would benefit him. And believe me, I don't like writing any of the above.
