Coups like that can happen due to organizations having a small number of board members that can decide to do as they like.

Proper mass-membership organizations are possible though. Same rules as a public corporation, but one vote per members, and the yearly meeting decides the board members and approves important decisions or introduce motions that steer the organization.

So the right way to do this would be to create something like the "Public LLM development club", some criteria on membership (after all entryism is a thing), some membership fee sufficient that there is money for a reasonable amount of work to be done and then one has to hope that people join.
