US government suing Facebook to wiretap Messenger
Facebook is reportedly contesting the request fiercely, as if it gives in, the much-vaunted privacy and security of communications within Messenger will be null and void, putting it at disadvantage against other forms of encrypted communication and creating a dangerous precedent in the process. Granted, the government has a legitimate reason to require wiretapping of the notorious MS-13 gang convos, but law enforcement has been known to overstep cell phone snooping boundaries.
Thus, the floodgates may open if permission is granted for one case, as end-to-end encrypted communication means just that - Facebook can't alter the software to snoop on its Messenger users, at least in principle. Messaging apps are so far excluded from the "fair and reasonable" demands of authorities for eavesdropping, but we'll see how long that will hold up, and the case against Facebook Messenger might very well be a harbinger of things to come.
