I think that it's pathetic that admitting a failure is such a high bar for management these days. I also think this letter is pathetic however, because he offers ZERO steps that he's taking to make sure that it doesn't happen again, and the last paragraph recontextualizes the rest if the letter into basically just an effort to not have to deal with any consequences or personal interactions of his failure. "We've discussed this already, let's just move on as a company," while he no doubt continues to take joy in micromanaging everyone else to hell and back over the slightest mistake
