Kpax,
One could reasonably assume that some of the powers that be also read this site, so in airing views we are getting exposure to problems. (If they don't, then they are even more ignorant of the people that work for them than I thought) However, this is done anonymously without having to stick your head above the parapet.
In a public forum there is nothing wrong with people sharing their views and/or experiences. If you don't like it, no one is forcing you to read it, after all.
