That doesn't make them public companies or ensure that they serve the public interest; it ensures that they cannot abuse their natural monopoly. Placing handcuffs on someone to prevent them from abusing others is not the same as someone who loves you. Examples that serve the public interest: charities, many non-profits Other examples of private companies that are constrained against abusing their power (apart from the obvious other utilities like gas and water): automobile manufacturers did not add seatbelts and airbags out of the goodness of their hearts, nor did they voluntarily improve fuel efficiency. New York City landlords are prevented from raising rents on rent-controlled apartments, in spite of how much they would like to. Factories that would love to pollute our rivers and streams... the list goes on forever.
