My experience more closely aligns with that of the article, and less so with yours. Having been in industry for over 20 years, and having watched the way it's been changing, I've come to the conclusion that the article has more truth than most people seem to realize.
Your experience is different from mine, and you are free to dismiss this as out-of-touch, mis-guided, or even simply wrong. However, my experience suggests that, broadly speaking, it's none of those.
The article all but explicitly states exactly what the parent comment wrote. Everything in the article is an elaboration on "humans are social creatures" and they act accordingly, in the article author's view (apparently) to maximize value for themselves (which is often the same as doing so for the company).
