If you don't like it, don't read it. It's on-topic and worth discussing -- maybe not for you, but this story is absolutely not within the criteria of flagging, which is why despite people flagging it, the link remains and will continue to be present on the site.
It's not really on topic. It's a personal grievance of the variety that anyone might have at their job. There's nothing about it that satisfies intellectual curiosity, and as demonstrated by the comments here, it's a topic likely to devolve into a flamewar. This shouldn't be surprising since it's impossible to make any argument from a logical basis. There is simply not enough information available from this one-sided blog post to have a meaningful discussion about it that isn't unfair to one side or the other.
