Google CEO Sundar Pichai posted a series of tweets that could be read as loose support for Apple's stance on the matter.
"Important post by Tim Cook. Forcing companies to enable hacking could compromise users' privacy," Pichai said. "We build secure products to keep your information safe and we give law enforcement access to data based on valid legal orders. But that's wholly different than requiring companies to enable hacking of customer device & data. Could be a troubling precedent."

Senior VP of Android, Chrome OS and Chromecast, Hiroshi Lockheimer, joined the debate.
Speaking with Bloomberg he said: "What we are talking about here is a completely different scenario, where we, the tech industry, or I guess in this case Apple, is being asked - it sounds like - to help in hacking their product. I think that is a very different scenario from the way things work today. I think that requires a lot of discussion and debate. It's an important decision."
"I have a lot of respect for law enforcement and of course I don't have any respect for criminals," he said. "That's not what this is about. I think it's more about a completely new way of thinking about things and we really need to debate that."

NSA whistleblower Edward Snowden, who exposed the worldwide surveillance programmes of the US and the UK, has said the technical changes demanded by the FBI would "make it possible to break into an iPhone (5C or older) in a half hour".
Snowden described the clash on Twitter as the "most important tech case in a decade" and that a win by the FBI results in an "insecurity mandate" - a "world where Americans can't sell secure products, but our competitors can".

Speaking at Mobile World Congress in Barcelona, Facebook founder and chief exec Mark Zuckerberg said the company is "sympathetic" to Apple.
"We believe in encryption, we think that that's an important tool," he said. "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."
He went on to say that Facebook has a "responsibility" to prevent terrorism and attacks, and that it's willing to take material that promotes terrorism from the service.
