Where can I get info on Telegram storing messages in plain text on their servers? I have asked and searched and all I have seen are hypotheticals but nothing concrete.
I've read through the audit they had in 2020 where cloud chats are encrypted using the same MT Proto 2.0 which they also use for the secret chats (E2EE).
The same way that evidence is available, I would also like to see the evidence of cloud chats stored in plain text and not encrypted.
