An anonymous reader writes with a story at IB Times that speculates instant messaging apps which enable encrypted communications (including Snapchat, Facebook Messenger and iMessage) could be banned in the UK
under the so-called Snooper's Charter
now under consideration.
The extent of the powers that the government would claim under the legislation is not yet clear, but as the linked article says, it "would allow security services like the Government Communications Headquarters, or GCHQ, and MI5, or Military Intelligence Section 5, to access instant messages sent between people to and from the country," and evidently "would give the government right to ban instant messaging apps that use end-to-end encryption."
That might sound outlandish, but reflects a popular and politically safe sentiment: "'In our country, do we want to allow a means of communication between people which we cannot read? My answer to that question is: "No, we must not,"' [Prime Minister] Cameron said earlier this year following the Charlie Hebdo shooting in Paris."
