I think it has something to do with what Steve Jobs identified - monopolistic companies don't value product folks, thus they end up getting run by sales and marketing people, and the company rots from within.
“The company does a great job, innovates and becomes a monopoly or close to it in some field, and then the quality of the product becomes less important. The company starts valuing the great salesman, because they’re the ones who can move the needle on revenues.”
