“Twitter is holding to a ‘principled’ policy on national security data requests and will ‘push back’ in some cases to protect the privacy of its users, its chief executive said Wednesday. Dick Costolo, appearing at a forum at the Brookings Institution in Washington, declined to comment on whether Twitter had specific requests under the vast data-gathering program called PRISM made public this month. But he noted that Twitter has gone to court in certain cases to fight ‘gag’ orders and to allow users to be in informed of how their own data is used.”
