In the week since Apple said it would do battle\u00a0with\u00a0the FBI over the agency's request for access to a smartphone belonging to one of the San Bernardino terrorists, tech industry leaders have been weighing in with their views.Most have come down in support of Apple, though others, including Bill Gates and Simon Segars, CEO of UK chip company ARM, have leaned more towards the FBI's position.Here's a roundup of what tech leaders have said so far, starting with some of the most recent views expressed.Bill GatesOn Monday, the Microsoft cofounder took issue with Apple's characterization that the government wants a "back door" to the iPhone.\u201cNobody\u2019s taking about a back door, so that\u2019s not the right question," Gates said. "This is a specific case where the government is asking for access to information. They're not asking for some general thing; they're asking for a particular case."The next day, Gates said headlines stating that he "backs the FBI" don't reflect his position."I was disappointed because that doesn't state my view on this," he told Bloomberg. "I do believe that with the right safeguards, there are cases where the government, on our behalf, like stopping terrorism, which could get worse in the future, that that is valuable. But striking that balance -- clearly the government has taken information historically and used it in ways we didn't expect, going all the way back to say the FBI under J. Edgar Hoover. I'm hoping now we can have the discussion. I do believe there are sets of safeguards where the government shouldn't have to be completely blind."ARM CEO Simon SegarsSegars, whose company designs the microprocessors in most smartphones, was asked his views\u00a0at Mobile World Congress in Barcelona.\u201cIt\u2019s a complex situation; there are rights and wrongs,\u201d Segars said.\u201cWe believe users should own their data and control who has access to it, but obviously there are some extreme circumstances where you have to look through a different lens."Mark Zuckerberg\u201cWe\u2019re sympathetic with Apple,\u201d the Facebook CEO said at Mobile World Congress in Barcelona on Monday. \u201cWe believe encryption is a good thing that people will want.\u201dIn a statement earlier, Facebook said the FBI's demands would create "a chilling precedent and obstruct companies\u2019 efforts to secure their products."Jan Koum, cofounder of WhatsAppKoum was among the first tech leaders to speak out, taking to his Facebook page\u00a0the day after Apple said it would oppose the FBI's request."I have always admired Tim Cook for his stance on privacy and Apple's efforts to protect user data and couldn't agree more with everything said in their\u00a0Customer Letter today," Koum wrote. "We must not allow this dangerous precedent to be set. Today our freedom and our liberty is at stake." IDGNS Sundar Pichai at Google I\/O in 2015Google CEO Sundar PichaiPichai soon followed with a series of tweets."Important post by @tim_cook. Forcing companies to enable hacking could compromise users\u2019 privacy," Pichai\u00a0tweeted\u00a0on Feb. 17.He continued: "We know that law enforcement and intelligence agencies face significant challenges in protecting the public against crime and terrorism.\u00a0We build secure products to keep your information safe and we give law enforcement access to data based on valid legal orders.\u00a0But that\u2019s wholly different than requiring companies to enable hacking of customer devices & data. Could be a troubling precedent.\u00a0Looking forward to a thoughtful and open discussion on this important issue."Twitter CEO Jack DorseyDorsey chimed in with a tweet\u00a0on Feb. 18.\u201cWe stand with @timcook and Apple (and thank him for his leadership)!\u201d Stephen Lawson Aaron Levie at the Box Dev conferenceBox CEO Aaron Levie\u201cApple\u2019s response to the government is something we completely, wholeheartedly agree with,\u201d the cloud storage CEO told TechCrunch. \u201cThe world is going to get more complex, so you can\u2019t create weaknesses in software that then will become vulnerabilities in the future.\u201dMark Surman, executive director of the Mozilla Foundation"Over the last year, we\u2019ve seen government agencies and law enforcement officials across the globe discussing policies that will harm user security through weakening encryption," Surman wrote\u00a0on Medium last week. "This includes the so called Snoopers Charter in the UK and calls by agencies like the FBI for tech companies to create backdoors into encrypted communications. ... While it\u2019s hard to discuss internet policy in the the context of horrific and tragic events, there is no question [the] FBI\u2019s request [is] an overreach. If granted, it both undermines everyday security for Internet users and would set a precedent for further weakening of encryption.Outside the tech industryWhile the tech industry largely supports Apple's position, the American public does not according to a study by the Pew Research Center. And there are plenty of voices outside of tech who back the FBI, including the White House, Donald Trump, and\u00a0William Bratton, the New York City police commissioner, who cowrote an op-ed in the New York Times Tuesday."Mr. Cook says Apple\u2019s ultimate goal is to provide customers 'safety' from 'attack," the op-ed reads. "But Mr. Cook does not seem to be talking about the kind of attack that took 14 lives in San Bernardino. Presumably, he means attacks from hackers or what he may view as government intrusion -- even when that intrusion is legal."
