I don't recall where I read about it, but my understanding is the developer lives a very frugal lifestyle in an off-grid environment, something akin to homesteading but with an internet connection. His costs are as minimal as he can make them, and in turn he can both spend more time on his work, and be fully commissioned with campaigns like this. I think he was also involved with the Debian GNU/Linux installer.
