His list implies a promise that he will not respond like this.
In quite a lot of work environments, being a bearer of "bad news" will often lead to getting your head chewed off. A certain level of trust is absolutely required for workers to be truly frank with their project manager.
Of course writing this on the net, I'm quite obliged to hold up the other part of the bargain. This is definitely part of the intent.
Thanks.

The points made in the OP are good, but saying that is easy. It's when the deadlines start blowing by that the real test comes as to whether he can actually live up to it and not start backsliding.
If they're not leading by example (as the writer says) then it's possible that "doing the right thing" and being communicative will eventually get you reprimanded, not rewarded.
Which is why it is important as someone who reports to others (most working folks do), it's important to make sure you know your management and choose (if possible) good management who you can trust and support your work-style.
