As lawmakers prepare to discuss the controversial Cyber Intelligence Sharing and Protection Act, or CISPA, Internet freedom activists are ramping up their campaign against it. On Wednesday, the advocacy group Fight for the Future published a video of Reddit co-founder Alexis Ohanian calling for online giants to speak up and fight against CISPA.

In the video, in which Ohanian unsuccessfully — and funnily — tries to get in touch with Google's Larry Page, the activist asks the search giant, as well as Facebook, and Twitter, to join his fight against CISPA. For him, the legislation goes too far and ignores Americans' right to privacy.

"I'm hoping that all of these tech companies take the stand, that their privacy policies matter, their users' privacy matters," he says. "And no legislation like CISPA should take that away."

CISPA, a controversial cyber security bill, has been recently re-introduced in Congress after dying out last year, when the House passed it despite a veto threat by the White House. The bill, however, was never picked up by the Senate and never reached President Obama's desk. CISPA is intended to allow private companies to more promptly share information on cyber attacks with the federal government, to improve and beef up defenses against cyber attacks.

On Wednesday afternoon, the House Intelligence Committee will meet behind closed doors for a markup session to discuss amendments that would make the bill more palatable for the White House and privacy advocates, who fear CISPA will allow private companies to share Americans' private information with the Government.

Fight for the Future has also launched a website, SaveYourPrivacyPolicy.org, to protest CISPA and gather public support against the legislation, in hopes of repeating the online uprising that helped defeat the Stop Online Piracy Act, or SOPA, a year ago.

The website has the Ohanian video embedded and also lets visitors tweet directly at Larry Page, and at Facebook's and Twitter's official accounts, with prepared messages like: ".@facebook did something right on privacy? @Google and @Twitter did what? https://cms.fightforthefuture.org/privacypolicy #CISPAalert."

Last month, it appeared Facebook withdrew its initial support for the legislation. And more than 30,000 other companies, including Reddit, Mozilla, Craigslist, and Duck Duck Go, have already come out against it.

According to The Hill, lawmakers will discuss various amendments Wednesday. One of changes would strip users' personally identifiable information when companies share cyber attack data with the government; another would strike down a provision that would have allowed the government to use the data received for national security purposes.
