i guess that fb does store keys after all; they do respond to police requests
i also found this: https://www.reddit.com/r/privacy/comments/v7tsou/is_whatsapp_lying_about_its_endtoend_encryption/
Encryption in WhatApp is actually a fake, because the encryption keys are generated and stored on Facebook’s servers, accordingly, they can read any of your messages as plain text, and the intelligence services obviously have access to them.
Also a few months ago there was a leaked slide from an FBI training course or something where they compared different messengers in terms of how well they cooperate with the police, guess who came first ?
WhatsApp provides data to the police in near real time (about 15 minutes from the time of the request)
The message from WhatApp at the beginning of the chat - that your data is not available to third parties is the height of hypocrisy.
I think it would be comparable to situation where all mRNA is suddenly unusable, ie protein synthesis can’t run at all. This would be something like ricin or diphteria toxin poisoning, but instead of being limited to gastrointestinal lining it’s spread all over. I’d guess hours to days before anything visible starts happening (symptoms only start to appear when deficit in new protein synthesis becomes noticeable; all protein already made continues to work for sone time)
