That may be naive. Most people have skeletons in their closets. The government would use these to pressure those leaders to acquiesce. I suspect the most dangerous skeletons are ones which seem harmless to you, but cast in the proper light they can be used as a justification for punishment. E.g. Something which seems harmless now can retroactively be used to claim you were doing insider trading. Few people would step up to defend you, even if the charges are baseless, because recently it's been fashionable to hate capitalists, and trading stocks is the epitome of capitalism. So it'd be very much "obey us or we will litigate you into bending your knee anyway."

Jobs was immune because he was the CEO equivalent of a rockstar. To try to pull baseless charges against him would outrage the public. Yet I'd imagine the public would get grim satisfaction out of seeing Ballmer punished, even if the charges were baseless, because most people don't like him. It's shallow, but it seems true.
