What's the chance that it is market motivated? That the companies most likely to succeed are those willing to break the rules (this isn't to say that breaking the rules makes one likely to succeed, you have to break the right rules and not the wrong ones, and that distinction is often times unknown til after the fact).

This might mean that the companies that we see explode in popularity are those whose cultures are already biased in ways that don't consider negative outcomes, as the companies that did consider them already excluded themselves from exploding in the market (they might still be entirely successful startups, but at a vastly smaller scale of success).
