Honestly, why do so many people, especially in the western hemisphere, act so shocked when somebody speaks their mind openly? To me this kind of communication says it comes from a real person who has real experiences, not the marketing department, and is understandably angry at the people who make his life worse. And it's natural to insult those people. Insults are a signal, not noise. They signal something is wrong and people should pay attention to it. I hear criticisms about being unprofessional and the like. So what? I don't wanna live in a world where everything everyone says is supposed to be filtered to match some arbitrary restrictions made up be people who more often than not can't do the work themselves. Almost all of the actually competent people I personally know speak like this. They can't stand those dragging us down through incompetence. They get angry when something that should work doesn't. They are driven by quality and will not be silent when it's lacking. If somebody fucked up, they will tell them they fucked up and have to fix it. And I much prefer that approach.
