The blog post says things other than "this was all my fault" (which, channelling Nancy G. Leveson, is not something we should ever say about the failure of a complex system), but it does very much say what you say it should say. The vast majority of the "mean things" in this blog post are polite descriptions of the facts; the remainder are rather mild expressions of frustration, plus one death wish against a hypothetical someone exhibiting an extremely obnoxious communication behaviour.
