Excellent add on to the thread. Powerpoint ronin have a sacred omertà. They often cross paths but never involve civilians in their disputes by revealing that one of them is full of shit - because both of them are full of shit.
In the tech world it's kind of a "game sees game" thing. Everyone is doing hyperstitional product marketing bullshit all the time, and calling any of it out is *rude* because everyone is supposed to support everyone else's grift all the time
