Right, but it's about the psychological state. Jimmy Wales made his money outside of Wikipedia. Linus wasn't doing Linux to get rich. If you read their bios, the Google guys weren't thinking about getting rich. Of all the recent crop of successful startups, maybe only Mark Pyncus was really focused on getting rich.

It's a bit zen but there is a good way to tell the difference. A successful startup founder, when presented with the choice between more money and more power, will take power every time.
