Wouldn't you want power to stay with elected officials who can be removed from office by the public rather than a private business that's primarily motivated by profit and only answers to shareholders.
Consider that politicians often operate against the will of ~49% of their constituents. As long as they can maintain a majority, they don't care as much about the minority. I don't think a company, operating in a healthy non-monopolized marketplace, would be as willing to lose 49% of their customers.
