PFF economist Tom Lenard says:

I supported the U.S. Justice Department's antitrust case against Microsoft, because I thought the evidence of its anticompetitive behavior was compelling. But I always opposed remedies that would turn Microsoft into a public utility and subject it to common carrier regulation. This is precisely what would happen if the Windows platform becomes subject to an "open access" requirement of the sort that some applications providers and antitrust enforcers now seem to want in the context of security software. It is hard to envision anything that could be worse for innovation in this critical, technically complex sector of the economy.

Others of us now at PFF still think the antitrust case was misguided nonsense, and are happy to see Tom back on the side of the angels.
