Microsoft sued the Justice Department Thursday in a case that will test broad principles of privacy in the digital age. But the root of the complaint is far more specific: Microsoft says the feds have demanded access to customer data 5,624 times in the past 18 months— and 2,576 of those demands came with gag orders that prevented the company from letting people know the US was snooping, reports TechCrunch. The government says it can do so under the Electronic Communications Privacy Act, but Microsoft argues that the law, written more than 30 years ago, is outdated and, worse, unconstitutional. The government “has exploited the transition to cloud computing as a means of expanding its power to conduct secret investigations," says Microsoft. What's more, 1,752 of the demands were open-ended, meaning the government can keep spying on someone for as long as it wants.
