Promises without consideration (e.g. unpaid) aren't enforceable. I help out by sweeping Amazon's yard everyday, for free. "Thanks!" they say, "Any time!" I reply. But years later, I decide to stop. Amazon cries out in anguish "But you have a Responsibility!", and threatens me that if I don't clean their yard... well, they'll do it themselves. Free maintained software suits Amazon, and some organizations / foundations provide it. Seems to work as consulting services advertising (BTW which incentivizes hard-to-use software, lots of complicated features, jumbled together... ever seen a large foundation's open source project like that?) Some businesses fund these foundations directly, but minimally, and there's a certain... reluctance. Perhaps an unmet need there...?
