Mark Zuckerberg said on Monday that he was “sympathetic” with Apple’s chief executive, Tim Cook, in his standoff with the FBI – but the Facebook boss left the door open to helping authorities fight terrorism and “different types of attacks”.

“If we have opportunities to basically work with the government to make sure there are not terrorist attacks, obviously we are going to take those opportunities,” Zuckerberg told delegates at the world’s biggest mobile congress in Barcelona.

“I don’t think that requiring back doors to encryption is either going to be an effective thing to increase security or is really the right thing to do. We are pretty sympathetic to Tim and Apple,” said the Facebook chief executive, referring to the US government’s insistence that Apple help it break into the iPhone of a mass shooter.



“At the same time we feel we have a really big responsibility running this big networking community to help prevent terrorism and different types of attacks.”



The controversy came into the public eye this month when Apple refused to help the FBI break into an iPhone belonging to Syed Farook, who along with his wife went on a deadly shooting rampage, killing 14 people in San Bernardino, California, in December.



Apple claims that cooperating with the probe would undermine privacy and security for its devices, while the US government counters it is a one-time request that will aid an important investigation.

Until now Zuckerberg – who has been at pains to plug privacy features on the social networking site in recent years – has not spoken publicly about the spat, although last week Facebook issued a statement in support of Apple.

In the statement, it pledged to continue “to fight aggressively against requirements for companies to weaken the security of their systems”, saying such demands “would create a chilling precedent”.



Apple has vowed to fight a judge’s order that it should create an operating system that would allow the FBI to force entry into the iPhone.

Last week Apple’s Cook also warned that complying with the order would set a dangerous precedent and open the door for governments and even criminals to access sensitive data in the future.

“Facebook and other large tech firms are global, and one of the things that they are concerned with is that when they make policy in the US, that policy is cited by other regimes, including non-democratic ones,” Avi Greengart of Current Analysis research firm said.

“There is also the real fear that once you ensure that encryption can be broken, it will be broken, because the tools for doing so will inevitably leak out – and that imperils security for personal information, business information, and transactions.”

Other major firms at the Barcelona congress have also sided with the iPhone maker.

Richard Yu, consumer devices chief for Chinese electronics giant Huawei, said Sunday that privacy was “the most important thing to the consumer”.

“We should really protect the consumer’s privacy and security. Personally, I support … Tim Cook’s idea,” Bloomberg News quoted him as saying.

Facebook was long accused of brushing aside users’ privacy concerns, and although Zuckerberg has strived to win back trust with a flurry of features, the social network is still in the eye of the storm.

Earlier this month, it was given three months by France’s CNIL privacy watchdog to stop storing data on people who do not have an account with the social network.
