A group of technology companies with a fondness for data collection have banded together to ask the US Supreme Court to stop the American government from snooping on cellphones without a warrant.

In a friend-of-the-court brief filed on Monday, Airbnb, Apple, Cisco, Dropbox, Evernote, Facebook, Google, Microsoft, Mozilla, Nest Labs, Oath (the company formerly known as Yahoo!), Snap, Twitter, and Verizon joined together in a fit of indignity. Aghast at government disinterest in privacy, they have urged the Supreme Court to make authorities collect cellphone data only within the confines of the Fourth Amendment.
