The presumption here is that doing open source work does not open doors to employment - in fact, that's quite far from the truth. It is in my experience that in large open source projects that anyone is impressed with, the people with commit privileges don't want more contributors. It is like Wikipedia where if you make an edit to their code or a replacement, they take personal offense to it and will fight you tooth and nail to get it ignored. Or in one case, just ignore me for over a year saying they will merge it and never do it. Or if they merge it, they don't give me credit.
