I disagree that this article assumes that product prevalence has "no bearing at all". That would be silly.<p>Rather, I think it merely demonstrates that product prevalence is not the <i>only</i> factor, and often not even the most important one. It dismisses the popular delusion that early success is all that is required to become an entrenched, inferior monopoly.<p>When high profile figures with political influence fall prey to these delusions -- even in the face of contrary evidence -- it bears a detailed criticism.
