Actually, you have to be careful when mixing monetary rewards with non-monetary rewards. It's possible that adding direct monetary payments can wreck the intangible rewards that are motivating others to work on something. I have seen instances of some projects decaying because of funding being applied in ways that other participants felt was unfair. It isn't simple. But it is perfectly valid to hire a programmer to add a feature to an existing open source project and to offer the work product back to the project. What doesn't work at all is attempting to guide a projects direction by playing political games with funding.
