This might be anecdotal but there is a ton of debate about whether or not Telegram is encrypted. This is not anecdotal though, on Wednesday night I saw an interview with a security expert on CNBC and he indicated that they knew that the riots in DC were going to happen because they had been "monitoring the extremists Telegram groups". What they didn't say was whether or not they were simply members of those groups, or monitoring from a "networking/technology" sense. I'm not sure if Signal does groups the same way that Telegram does but that one is widely believed to be much better than Telegram as far as privacy and security. Telegram is a tremendously useful (and free service) for connecting to Elastalert for all manner of notifications, but we have since moved to Teams for that just because we can't really be sure what is going on under the hood with Telegram. Just some things that I have observed, not trying to start a holy war.
My rudimentary understanding of Telegram is that group messages are client-server, which is why new members can read old posts when they join a group.
Signal, on the other hand, is p2p for members within the group. No messages are ever sent to their cloud.
