Facebook's Mark Zuckerberg: US 'blew it' over NSA leaks "The morning after this started breaking, a bunch of people were asking them what they thought," Mr Zuckerberg told a technology conference in San Francisco. (They said) 'Don't worry, we're not spying on any Americans.' Wonderful, that's really helpful for companies trying to work with people around the world. Thanks for going out there and being clear. I think that was really bad. Mr Zuckerberg said Facebook would continue to press the authorities to be allowed to reveal more details about the information being sought by the NSA. There were around 9,000 such requests from the government in the first six months of this year, but it was not clear how many of those were from the NSA. Facebook and other internet companies including Google, Microsoft and Yahoo have filed legal actions seeking permission to give more details. Speaking at the same conference Yahoo chief executive Marissa Mayer said the company could not reject NSA requests because "if you don't comply, it's treason." But she said the company was "sceptical" and had been "pushing back a lot" against the requests. She added: "It makes sense for us to work within the system." Mr Zuckerberg, who visits Washington DC next week to speak with leading Republican politicians, said: "We've been pushing just to get more transparency on this and I actually think we've made a big difference, "We're not at the end of this. I wish the government were more proactive about communicating. We're not psyched that we had to sue and we take this really seriously.
