Key technology companies including Google, Microsoft and Twitter on Friday filed in support of Facebook’s dispute with the New York County District Attorney’s office over the collection of user data in bulk under a gag order for a fraud investigation. The New York Civil Liberties Union and the American Civil Liberties Union also filed an amicus curiae brief Friday in support of the Facebook plea. Facebook said in June that a court in New York directed it to turn over to law enforcement virtually all records and communications for 381 accounts, including photos, private messages and other information. The social networking company was also prohibited from informing the targeted persons who included “high schoolers to grandparents, from all over New York and across the United States.”
