I program for free, nowadays. I made enough, as a manager (which I hated), to be able to retire early, at a fairly humble level (which was a good thing, because no one wants to hire "olds"), and I do work on nonprofit stuff.
The project I'm working on now, would make a lot of Fortune 100 companies green with envy, and I'm doing it for free.
