Google: "Google cares deeply about the security of our users' data. We disclose user data to government in accordance with the law, and we review all such requests carefully. From time to time, people allege that we have created a government 'back door' into our systems, but Google does not have a backdoor for the government to access private user data."[112] "[A]ny suggestion that Google is disclosing information about our users' internet activity on such a scale is completely false."[113]
Apple: "We have never heard of PRISM. We do not provide any government agency with direct access to our servers, and any government agency requesting customer data must get a court order."[115]
