Well, if you squint a little bit, this all looks kind of like a military coup. Through the cultivation of personal loyalty in his ranks, General Altman became able to ignore orders, cross the Rubicon, and subjugate the senate. It's an old but common story.

I point out this similarity because I suspect that the corporate solution to such "coups" will mirror the government solution: checks and balances. You build a system which functions by virtue of power conflicts rather than trying to prevent them. I won't pretend to know how such a thing could be implemented in practice, however.
