Volunteering is all about taking responsibility. If you contribute regularly to a project with many users, you can't avoid the responsibility. If you only want to express yourself by writing code without the burden of responsibility, you should contribute to something else.
One thing I've learned from various volunteer projects and organizations is that good volunteer administrators are rare. Finding good people for the creative parts of the project is not particularly difficult, because creative work is inherently satisfying. Administrators are another story. Many try the job and quit, because they don't enjoy it enough to do it in their free time. Others are not suitable for the role. Some are good and motivated administrators, but they drive other volunteers away by trying to manage them. And then there are the rare ones who can be administrators and enjoy it without ruining the project for everyone else. If you manage to find one, the last thing you want to do is increasing their burden.
As far as I understand, PyPI is largely a volunteer project. It works only because some people find running that kind of bureaucracy satisfying. It's their project, and they can run it any way they want. If their burden gets too heavy, they may quit, and then the project may fail. That would probably be a bigger issue than some open source contributors not liking how PyPI is run.
