Bob Harp is featured in the article prominently, so I'm not sure how it can be "potentially misleading" as to his role.
The whole point of this article is to highlight what was different about this situation. Bob Harp's contribution wasn't particularly unique! There were lots of highly competent engineers in the early PC industry doing stuff like this. Read Stan Veit's book or "Fire in the Valley" if you want more than you'll ever need to know about them.
