Heck, I remember my first visit after a while. The and was asked what I have been up to lately - I said I became a developer with the open-source #OpenBSD project. First question was how much are they paying me. When I told I'm doing it for my own and public benefit they could not believe 'that I'm wasting time with this'.
Yet in the end, they just expect a tool fitting their needs being ready made by the open source community.
