This example will make a good lead-in for any argument to abolish the FCC or other regulators. When encountering passages like, "Within a few years of the FCC's Carterfone decision, America had become a motley world of funny receivers, slick switch boxes, and rickety answering machines," always my question is "What would the world be like now if we had gotten a few years head start on such development?"
And very often people will bash free markets with examples of corporations like that, but few will point out that there is a big difference between the corporatism we live in and truly free markets.
