And the incentive for Congress to save a technology that gives wider exposure to their foibles (and worse), allows people to organize on issues and for opposing candidates, and puts constituents one email away (instead of the old four days for a USPS letter) is what?
Few groups have a greater incentive to see the internet regulated than sitting members of Congress.
The internet is, in the final analysis, an open system of communications available to anyone with the expertise and resources to use it. If ICANN goes the way of the DODO another system will replace it in sort order. The WWW cannot be controlled. Totalitarians can restrict some of its activity for a sort time but the traffic is such a blizzard of motion those restrictions become meaningless in short order.
