Since there are no barriers in open source, it has to be a self-inflicted problem. You can start just now. Pick a project or start your own. Not every developer contributes either. Aside from that anonymous open source contributions are plentiful, so maybe it isn't even true. I don't believe any barrier aside from the technical one exists here or even can exist because there is no authority that could keep anyone out.
> women and other gender minorities
Women aren't a gender minority.
> Enforced codes of conduct matter
I don't think so, you want OSS to cater to you. You sell yourself to companies that want to enforce compliance and you are the useful vehicle. This is why you get animosity, not because of your sex.

I dismiss this because there is no evidence at all.
> Open source leadership
You didn't even understand the concept.

I think I need to make an example of people trying to enforce some compliance or demands without any contribution, a common problem in OSS.
