I think it is unfair to call "contributors" charity workers when all they do is cause headaches for the oss project leaders. The project leader won't be a jerk to you if you make a nice well-tested, style-adhering commit that only addresses a single issue without breaking other code. Don't think for a second 'occasional contributors' combined efforts even come close to the contribution of even a single project leader.
