As noted by the folks over at Techdirt:
Just as NBC Universal and other SOPA supporters continue to insist that DNS redirect is completely compatible with DNSSEC… Comcast (and official SOPA/PIPA supporter) has rolled out DNSSEC, urged others to roll out DNSSEC and turned off its own DNS redirect system, stating clearly that DNS redirect is incompatible with DNSSEC, if you want to keep people secure. In the end, this certainly appears to suggest thatComcast is admitting that it cannot comply with SOPA/PIPA, even as the very same company is advocating for those laws.
