Developers sometimes seem to be as in control as farmers are of the distribution of their produce. There's no absolute rule that gives the owners of large scale distribution networks power over both producer and consumer. It's just laws of convenience. It's easier for everyone to go through a few or just a single common broker.
There's no law against a more democratic way to implement the broker either but it requires interesting methods of coordination and/or decision making that doesn't seem to exist yet?
