>I wanted to object (as a happy Telegram user) that I want to preserve message history for all my devices...

Telegram is already useless on that score. Since the other party/ies in a conversation can delete their messages from everyone else's devices as well as from their own. I stopped taking any of Telegram's privacy and security claims seriously when i discovered that gem.

I still use Telegram to keep in touch with a load of family and friends but I have no faith in whatsoever any of their self-righteous privacy & security claims and comparisons with other messaging services. For a very long time now, evey update has focussed on adding moronic cutesy junk like animated emojis and stickers. So it's quite clear that their focus has moved away from being a private & secure messaging service and towards appealing to the TikTok generation.

That's fine. It's their project. They can do what they want with it and [as I said] I still find it useful. I just wish they wouldn't keep on trying to convince people it's a serious secure commmunication tool.
