@neil I agree, I'm talking about the actual power structures of the organizations. Debian is a constitutional democracy of its core contributors that have agreed to put users and free software first as a community: "Our priorities are our users and free software"

Users do not have a vote. From what I've heard, Wikimedia Foundation is similarly controlled by the volunteer editors.

Do you know of any free software project where users have a defined binding vote?
