The event that has gripped the tech and libertarian community over the past 48 hours has been Tim Cook’s stern refusal to comply with a subpoena demanding that Apple unlock the iPhone 5C belonging to one of the San Bernardino shooters for a full FBI inspection.

As reported previously, Judge Sheri Pym of U.S. District Court in Los Angeles said on Tuesday that Apple must provide “reasonable technical assistance” to investigators seeking to unlock data on – in other words hack – an iPhone 5C that had been owned by Syed Rizwan Farook, one of the San Bernardino shooters.

So far Tim Cook has refused to comply, saying said his company opposed the demand from the judge to help the FBI break into the iPhone. Cook said that the demand threatened the security of Apple’s customers and had “implications far beyond the legal case at hand.”

He added that “the government is asking Apple to hack our own users and undermine decades of security advancements that protect our customers — including tens of millions of American citizens — from sophisticated hackers and cybercriminals,” he said. “We can find no precedent for an American company being forced to expose its customers to a greater risk of attack.”

Cook’s summary:

“The implications of the government’s demands are chilling. If the government can use the All Writs Act to make it easier to unlock your iPhone, it would have the power to reach into anyone’s device to capture their data. The government could extend this breach of privacy and demand that Apple build surveillance software to intercept your messages, access your health records or financial data, track your location, or even access your phone’s microphone or camera without your knowledge.”

On the surface, this appears like valiant attempt by the CEO of the world’s most valuable company to stand up against the Big Brother state made so famous in the aftermath of the Edward Snowden revelations.
