This is silly - authority in a software community doesn’t come from a nonprofit charter. Being founder is also no guarantee of authority, but it is more relevant because it’s rooted in actions and outcomes.
The more I observe from the sidelines of open source the less attention I pay to these sorts of disputes. In the end they are all adjudicated by delivering useful software and updates quickly to end users. Whoever does that better “wins.”
Sometimes this is the founder of the project and sometimes not. In general I think it’s a mistake to think anyone cares all the much about anything beyond the license, capabilities of the software, and how quickly the community/maintainers fix bugs. They may say they do but people who are taking software for free are in no position to dictate much and at the end of the day they know and accept it (especially something like who sponsors a conference, who is the keynote speaker (Rails incident) etc)
