"Making Money in Open Source" can have several meanings. Selling software is just what most people think of when reading the title. I myself can say I made about $150k in Open Source this year. But it wasn't by selling software, it was by doing freelance jobs and consulting that involved free software only. Money wasn't coming in on autopilot, I had to get up every day and go to work at several places. But for me, free software is the reason I live a very comfortable life, doing things I love to do. It just isn't selling software, but everything else around it. I always tell my friends that I am the perfect example that Open Source brings in more than enough money.
I can't figure out how the license on the software is relevant to this story. It seems like you could just as easily tell this story to relate how well a lucky money-making charm works. The charm did not make you money; the hours you put in consulting did. I mean, this doesn't give me any reason to open-source any software I write outside of a specific contract to do so.
