The IT industry is full of crotchety neckbeards with chips on their shoulders who need to be tiptoed around, generally with good reason because when others participate in the work they have created, they feel devalued and lash out. An apology would never serve to satisfy because there is an inherent criticism underneath all this implying that Grubers initial work was less than perfect. That's what he's probably actually angry about, not the mecanics of the process for coming up with a less inconsistent and better defined standard. Failing to reply to Jeff's emails is standard passive-aggressive behavior for people like this. It puts him in a position to shout about how he has been wronged.
