Most people don't do it because it's effort that's not directly associated to programming. It's also easy to think that you won't get any payoff from the effort invested, since it's rare to see to begin with, and even more rare to see anyone making a decent living off of it.

More financial support to free software development would certainly be appreciated. Even a single cent just to show the developer you enjoy his software is a good incentive for a developer to keep going. It seems like most feedback developers get is negative, so anything positive is appreciated.
