I don't think that most requests by OSS users are unreasonable or unfair. Anyone who puts out code that is not perfect (i.e. all code) should expect there to be bug fix requests, support questions, documentation requests, and suggestions for new or better features. But even if you say NO to the vast majority of requests, it generally requires some real time and effort to address each one. If the originator does not feel like 'maintaining' a project and their is no financial incentive for doing so; then I think that can be a big barrier for many projects and can prevent them from being open sourced to begin with.
