A group of 47 companies, including Apple, Google, Microsoft and WhatsApp, have criticized energetically a proposal from the UK intelligence agency GCHQ to spy on encrypted messages. In an open letter published in Lawfare companies say the plans would undermine security, threaten trust in encrypted messaging services and, ultimately, endanger citizens' right to privacy and privacy. the Liberty of expression.
The GCHQ proposal was first published last November as part of a series of essays, and does not necessarily reflect a legislative agenda of the intelligence agency at this time.

They say the proposals would require messaging applications to change the way they use their encryption, and I need to trick users by hiding messages or notifications about who is present in a chat.
In response to the open letter, one of the original authors of the proposal, Ian Levy, of the National Cyber Security Center, said the proposal was "hypothetical" and that it was only intended "as a starting point for the discussion". In a statement sent to CNBC Levy said: "We will continue to work with stakeholders and hope to have an open discussion to come up with the best possible solutions."
