Nothing in the comment linked upthread is at all relevant to the analysis of Telegram we are discussing.
This was not a case of a user confusing encryption in transit, as you claim.
Do not use Telegram.

Telegram does not store messages in plaintext.
Your claim:
> That user seems to be misinformed, and appears to be discussing client-server encryption, not end-to-end encryption
Is categorically false. You do not get to redefine what encryption is. That is not your right.
You've been corrected repeatedly. If you continue to insist you have not made a false claim, you are then lying.
