I actually see this rather as evidence of a strong corporate culture which recognizes the need for execs to take responsibility for mistakes, as the chapter from the Lashinsky book on Apple management famously quoted about the rubric being crossed when VP's are promoted: http://www.businessinsider.com/steve-jobs-on-the-difference-...

(Kinda wish a few more companies made this expectation clear... too much deadwood at the VP level in many IT companies I deal with...)
