> My understanding is that there has been very few improvements that they weren't dragged into. imho telegram is a reckless tool from a cryptographic point of view, and still highly suspect Again, I cannot speak about the crypto but I can speak about - bugs: last time Telegram had a know bug where data could realistically leak except inside Telegrams infrastructure (which of course is a big deal) was around the time it launched as far as I know. Looking at Signal (which I recommend for anything super secret) they've had a couple of really nasty bugs in the much shorter life time: RCE in desktop client and spuriously sending images to persons except the intended recipient is just two. - things they haven't been dragged into: anti-hijacking, deletion on account inactivity, working backup, not syncing secret chats between clients and more.
