EXCLUSIVE: Internet sites on their SOPA-Strike may be conducting a blackout but Hollywood studios are conducting a boycott. I’ve learned that Hollywood studio chiefs individually and as a group are drawing a line in the sand on the piracy issue with the Obama re-election campaign and refusing to give any more donations.  The blowup came after President Obama on Saturday dashed moguls’ hopes that he would remain on the sidelines in the dispute over the U.S. House Of Representatives’ Stop Online Piracy Act and the U.S. Senate’s Protect IP Act. In a posting on the White House web site, three of the Obama administration’s top officials for Internet and intellectual property matters said that  they share many of the concerns that the Internet community has about the Hollywood-supported bills. The trio said that they “will not support legislation that reduces freedom of expression, increases cybersecurity risk, or undermines the dynamic, innovative global Internet.” Intellectual Property Enforcement Coordinator Victoria Espinel, U.S. Chief Technology Officer Aneesh Chopra, and Special Assistant to the President Howard Schmidt tried to soften the blow to Hollywood by acknowledging that that online piracy is “a serious problem that requires a  serious legislative response.” They added that they plan to host an online event “to get more input” on the matter. But Hollywood moguls told me they “didn’t know it was going to be as over the top as it was” and took this as a declaration of war. “We just feel very let down by the administration and Obama for not supporting us,” one studio chief explained to me. “At least let him remain neutral and not go against it until we can get the legislation right. But Obama went against it. I’m personally not going to support him anymore and not give a dime anymore,” another movie mogul who’s also a well-known Obama supporter told me this week.
