Apparently you've avoided one of the greatest joys of open source... forks.<p>I worked for 7 years on an open source project with hundreds of people subscribed. My most trusted maintainer started a drumbeat about project goals that ended up causing two forks, decimating the user community, and destroying a lot of potential. Even more interesting is that all I ever seem to get, if I get mentioned at all, is negative press. But, as John Gorka once said, "What matters most is what you do for free".<p>As for the worry about combining open source and money... forget it. William Stein, lead developer of Sage, built Sage using grant funds and graduate students. Unfortunately the grant money dried up and the students graduated. He has since taken a leave of absence and started a company in the hope of keeping the project alive. Wish him luck.<p>I've looked for funding from a number of different sources, government, industry, and a separate business, all without success. I spent an average of $3,000 per year for the last 16 years, all out of personal funds. That's assuming my time is $0/hour.<p>Rest assured, mixing open source and money is the least of your worries.<p>So why do open source programming? Real musicians MUST make music, in spite of poverty wages. It's not what they DO, it's what they ARE. Similarly, I'm a programmer... it is what I am, not what I do.
