I think the more important thing to talk about is that everyone calls Telegram "secure", but by default it's not E2EE. Which in the best case is PR and the worst case a honeypot.
There were two big discussions on that topic recently:

What a weird site, can't seem to scroll it? It wants to install some weird app?
