They already have control. I for one would rather have an occassional tyrannic majority than several everpresent tyrannic minorities. Personally, I'm not worried about an overlording majority - there are so many aspects of the DNS problem that I seriously doubt that any majority for one issue will remain a undivided majority once another issue rolls around.
Businesses are always in a good position to nudge their employees.
That ability to decide represents a big source of power. The argument has been made that the existing constituencies will resist change. I don't think that that is the case. My own sense is that the DNSO has gone bust and that it will continue to be bypassed as a policy making body until it is reformed. The sense that the DNSO has lost credibility is manifest in the way it has been left out of nearly all of the major DNS policy decisions of the last 18 months.
