Annoying and hurtful, yes, but at the same time, he's not wrong - you fucked up, you did bad and you should feel bad. The upside of this rant too is that the author is not "fired", as such, but told to shape up or gtfo. In a lot of companies, mistakes are accepted, fixed, and forgiven without adding a bit of emotion to it. I think adding this kind of emotion will have a bigger impact and will make the receiving end do better.
