But I disagree that he could have done anything bad. What's the worst thing a monopolist can do? Charge unfairly large prices. By the time his the government got around to breaking up his "empire" for the politicians' own venal reasons, the global market had grown so large, that he already couldn't service it all himself. If he had raised prices as his end-game, the forces necessary to capitalize on that opportunity were already deployed and ready to strike at his market share.
The only dictator I see in the picture are the politicians/regulators who broke it up for their own political gain. Those are the dangerous ones because no matter what they do, we can't shop elsewhere.
