I was kind of surprised by that remark of Dirk's as well. He said people were working on open source because they are paid for it; but even if I'm paid to work on free software, that's only because I was passionate enough about free software to make it my job, after many years of putting in an enormous amount of spare time
It almost sounds as if as soon you're paid for it, it stops being a passion and is done just for the money.
And even then... In the evenings and weekends I still work on open source as a volunteer, for Krita. So I am in both positions. How should I be counted? 0.5 volunteer, 0.5 corporate paid drone who accidentally works on free software?
I think this whole "don't think that open source is still an idealistic volunteer movement -- people are paid to do it!" idea is a fallacy. Even when it's said about the Linux kernel, but even more when it's said about a project like KDE.
