Slightly off topic, but I strongly believe that the rise of "professional" CEOs was the beginning of the end for quality products and services. Before, you were generally an expert in your particular domain and was invested in solving the customer's problems.

> If CEOs were legally required to regularly use their own products as an ordinary customer, the world would be a better place.

This is like the argument "developers should use the software that they write" (dogfooding).

Let me give one example: the previous person who designed and developed the previous version of the software which I now work on really could use "his" program insanely well. The problem was rather that he was basically the only person who really did understand it sufficiently well to not to be triggered by problems other users had. Yes, a huge part of my job is over the years to turn this piece of software into something that is understandable by other people, too,. :-)
