Economically, I look at work I do on Free/Open Source software as an investment in reputation capital. In this case past such investments paid off with yet more work on FLOSS, which is a nice virtuous cycle to be in.
I'd love to know how you went about this.

It's struck me for a long time that Free Software offers a bit of both. It minimizes business costs (both direct license expense and licensing-derived limitations on use), while maximizing functional capabilities.
It doesn't entirely surprise me that someone as familiar with the concept as Joey Hess would extend this to his personal life. A $1.5k/year nut buys a hell of a lot of F-U freedom.
