I find it hard to believe that your generalization holds for all of the thousands of Open Source projects, or even for the majority of them. I mean that they treat women worse than men. Got any pointers to studies, references that make you think so?
As for no hand-holding, this would equally harm men and women. Sure, hand-holding would be nice, but what if it isn't really in the budget?
And what if women would START open source projects? Then they could decide on all those aspects. You don't have to ask anybody for permission to start an OS project. So we should see high rates of women starting OS projects, compared to women joining existing OS projects?
