Every single time one of those has been posted here on HN, there's been ignored backstory to the outburst. Usually there's a fair amount of polite conversation before it, then he gets frustrated and vents. If you actually poke around at what he says day-to-day, it's really not the way he is - it's just clickbait articles that paint him that way, being sure to present him out of context.
Stop reading the clickbait. If everything that has happened in your office was posted online, you could probably be made to look like a much worse monster.
