I think we need to stop centering capitalism entirely, and start concentrating specifically on the process of how decisions are made. Collective deliberation, and the rules around it, seem to just be waved off when they are the substance that democracy and collective ownership are made of.
Whether that group is profit-making or not, it's the decision-making that's important. Who gets a say, how is what has been said handled, and how does that affect the allocation of resources and the direction of movement?
edit: FOSS has a "benevolent dictator" problem and is obsessed with either praising them or tearing them down. A stable organization fluidly changes leadership without changing character: it should only change character when the membership changes, with the consent of the previous membership. The ability of FOSS to simply fork puts it in a blessed position to follow this strictly (and still maintain a friendly relationship between forks.)
