This story is a bit misleading. If you study the successful companies using open source as a business model you will find they all raised large amounts of venture capital. That was during the window when open source as a business was a brand new idea.
That window has now all but closed and it is exceedingly difficult to find examples of successful companies that bootstrapped their way to success running an open source business.
