Whereas we would have nothing to fear from a private Internet monopoly, unrestrained by any regulation enforcing net neutrality or the constitutional limits that apply to government. The executives and shareholders of such a monopoly would realize their civic responsibility to uphold the free expression and exchange of ideas among the citizenry, and would readily uphold that responsibility even if it meant taking a hit on the bottom line.
That's the way it is in the Bizarro World, anyway. In this real world, an unregulated entrenched monopoly/oligopoly has all the power of government with none of the accountability.
