The flaw is that young idealistic techies and would-be business people keep making the mistake of believing you can grow a large multinational corporation that doesn't end up becoming at least slightly evil. The evil is inherent in the scale and structure of these entities and it comes from the bureaucracy of many competing and self-defeating business incentives and the ultimate decision/realization that "making more money" is the only sane holistic goal to globally optimize for. Simply deciding that your company will contribute to open source or have some motto like "don't be evil" is not enough to avert this pitfall.
