jfruhlinger writes "In a political environment that's become very strongly defined by partisan lines, the SOPA debate has offered an unexpected ray of hope: the two main Congressional opponents of the bill are Ron Wyden, an Oregon Senator deemed a 'hardcore liberal' and Darrell Issa, a California Representative who is one of the Obama Administration's fiercest critics. (There are both Ds and Rs in favor of the bill, too.)" (Read more below.)In the technical rather than political world, opposition seems easier to find: Trailrunner7 writes "A group of engineers, networking specialists, security experts and other specialists deeply involved with the Internet's development and growth have sent a letter to lawmakers criticizing the highly controversial SOPA and PIPA bills and imploring them not to pass the legislation, which they say would stifle innovation and 'threaten engineers who build Internet systems or offer services that are not readily and automatically compliant with censorship actions by the U.S. government.' The letter is signed by a long list of Internet pioneers and other respected figures, including Steve Bellovin, Paul Vixie, Vint Cerf, Jon Callas, Tony Li, Robert W. Taylor, Esther Dyson and Fred Baker, among many others. Both SOPA and PIPA have been criticized heavily by technologists, privacy advocates and security experts who say that not only would the proposed bills make it difficult for companies to create innovative new technologies, but they also would likely not even accomplish the goals their authors' had in mind, namely preventing copyright infringement and content piracy."
