Apple of course shouldn't be in this list at all, Wozniak was never a CEO and I'm sure he'd be terrible. I'm also not sure many of the others qualify either, were Sergey and Larry "good CEOs"? As others have noted, the correlation between developer CEOs and success is that many of the most successful companies today are software companies. Is there even a single large non-tech company with a developer as CEO? If anything I would assume developers are substantially worse than average as CEOs, from lacking interpersonal skills to exaggerated focus on details.
