Is the Joomla! community a democracy?
From Joomla! Documentation
Generally speaking, the Joomla! community is not a democratic organization and it has never presented itself as such. Occasionally, the Core Team asks the community to vote on things as a whole but this tends to be a pretty rare event. However, the community’s input and feedback are welcome and carefully listened to.
Official team members (who are registered as such in the Volunteer Portal) in Joomla do get to vote on their team leader as well as the Open Source Matters officers on the board.
