(CNN) -- The co-founder of the popular social news site Reddit has called on the leaders of Google, Facebook and Twitter to help defeat a controversial cybersecurity bill that would compromise the privacy of their users if passed by lawmakers. "I'm hoping that all of these tech companies take the stand that their privacy policies matter, their users' privacy matters, and no legislation like CISPA should take that away," Alexis Ohanian, former owner of Reddit (Wired's parent company Conde Nast currently owns Reddit), said in a video posted last week. "If someone wants access to our private home or to our mail we would say, Well go get a warrant. Right? CISPA basically says, uh, not necessary. Your digital privacy is irrelevant."
