The Guardian: Facebook among tech firms battling gag orders over government surveillance by Olivia Solon:
Tech companies including Facebook, Twitter and Microsoft are fighting gag orders from US courts preventing them from talking about government surveillance of their users, arguing it has a chilling effect on free speech.
Facebook, Twitter and Microsoft all have policies to notify users of government requests for account information unless they are prohibited by law from doing so in exceptional circumstances such as life-threatening emergencies, child sexual exploitation and terrorism.
However, it seems that the US government is attaching gag orders – many with no time limit – to their data requests in about half of all cases. This means that people are having their digital lives ransacked without their knowledge and with no chance for public scrutiny or appeal.
