An anonymous reader writes: Edward Snowden, the whistleblower whose NSA revelations sparked a debate on mass surveillance, has waded into the arguments over the FBI's attempt to force Apple to help it unlock the iPhone 5C of one of the San Bernardino shooters. The FBI says that only Apple can deactivate certain passcode protections on the iPhone, which will allow law enforcement to guess the passcode by using brute-force. Talking via video link from Moscow to the Common Cause Blueprint for a Great Democracy conference, Snowden said: "The FBI says Apple has the 'exclusive technical means' to unlock the phone. Respectfully, that's bullshit." Snowden then went on to tweet his support for an American Civil Liberties Union report saying that the FBI's claims in the case are fraudulent. Apple's clash with the FBI comes to a head in California this month when the two will meet in federal court to debate whether the smartphone manufacturer should be required to weaken security settings on the iPhone of the shooter.
