The biggest Internet presence in the world will have something to add to the growing online protests against anti-piracy legislation, though they won’t go as far as shutting down their operations. Google plans to highlight the issue with an action item on their famously spare homepage.

Despite the fact that SOPA looks dead in the House, PIPA, the Senate’s version of anti-piracy legislation, hasn’t gone anywhere. It’s true that six Republicans wrote to Harry Reid asking for a postponement of the bill. Now Wikipedia will join others in shutting down on Wednesday to protest the bills.

Pressure on House Republicans may have doomed anti-piracy legislation for the year. Darrell Issa, who along with Ron Wyden has been out in front of the opposition to SOPA and PIPA, the respective bills on this issue, says that he secured a promise from House Majority Leader Eric Cantor that no bill will hit the House floor without “consensus.”

The reaction to SOPA and PIPA, the latter which is scheduled to get a vote in the Senate when they come back to Washington, is not a Statement of Administration Policy, nor does it truly grapple with the legislation itself. Instead, the three Administration officials – IP Enforcement Coordinator for OMB Victoria Espinel, US Chief Technology Officer Aneesh Chopra, and Cybersecurity Coordinator Howard Schmidt – lay out broad principles for what legislation to combat online piracy should look like. They do say that this statement of principles will guide “what the Administration will support—and what we will not support.” So it’s worth reading closely.

In what looks like a victory for the grassroots anti-Internet censorship coalition, the sponsors of two bills moving through Congress, PIPA (Protect IP Act) in the Senate and SOPA (Stop Online Piracy Act) in the House, have agreed to remove or water down controversial provisions that would require ISPs to block domain names that engage in IP theft or piracy.

The opposition to a pair of copyright protection bills that could lead to Internet censorship has grown over the past week. The Online News Association delivered its opposition to the bills, joining the American Society of Newspaper Editors, the State Department is backing off, and the GOP’s Paul Ryan has announced his opposition. But there’s little mainline news coverage.

Let’s define some terms here. The Internet censorship bills have different names depending on which chamber of Congress you’re talking about. The House bill is called SOPA, the Stop Online Piracy Act. That bill is currently in the committee process and has not yet cleared the Judiciary Committee. Observers thought this would happen at the end of last year, but House Judiciary Chairman Lamar Smith cancelled the conclusion of the markup at the last minute.

But in the Senate, the Judiciary Committee has already cleared their version of the legislation, known as PIPA, the Protect Intellectual Property Act.

The dynamic is clear. Once SOPA (and its Senate counterpart Protecting IP Act, or PIPA) became high-profile among the Internet community, the lazy endorsements from companies and various hangers-on became toxic. And now those supporters are scrambling, hollowing out the actual support for the bill. Suddenly, a bill with “widespread” corporate support doesn’t have much support at all. And remember, the corporate support was the only thing propping up SOPA; it’s not like there’s a grassroots army urging Internet censorship.

When the House Judiciary Committee adjourned without a final vote on the Stop Online Piracy Act, the expectation was that they wouldn’t take up the matter again until next year. HJC Chairman Lamar Smith appeared to agree to allow technical experts give testimony on the implications of the bill to the Internet’s architecture, particularly the Domain Name System. But quietly, Smith announced a resumption of the markup for this Wednesday, at a time when Congress may not even be in session.

The House Judiciary Committee abruptly adjourned today without completing work on the Stop Online Piracy Act, an unexpected twist in the high stakes battle between Hollywood content providers and leading Internet companies.
