Perhaps I don't know enough of what goes on behind the scenes, but I can think of a bunch of witnesses who have helped solve a lot of problems, at least as far as I can see.
If he wants to have some influence over who the witnesses are, there are other ways he could do it that give more say to the community than just dominating it himself as the majority shareholder.
As far as driving people off the platform, I can think of far more people who caused problems who have been tamed than decent people who were driven off the platform, although once again, I don't know a lot of what goes on behind the scenes.
