I’m from Mexico, and the most used chat application is WhatsApp. It’s used for EVERYTHING. I use Telegram only for contacting my family members (both my parents and my brother). They also use it only for this family chat. All my (and their) contacts use WhatsApp instead.
Now with the news that Telegram will collaborate with Twitter, I feel that I should delete it. Not that Zuck is any better than Musk, but still…
Also I don’t think it’s worth the effort to teach my parents yet another messaging app, like signal.
No default end-to-end encryption (only in Secret Chats)
Messages stored on Telegram servers, not fully private
Uses custom, less-proven encryption protocol (MTProto)
Server-side code is not open source, reducing transparency
what is the case of encrypted secret chats? are they stored in server, or in devices.
Should just be on device
