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.
I really distrust telegram. There are some many dark patterns around it and the server is closed source so I’d say the distrust is very well deserved.
has there been cases where telegram chat been leaked/compromised?
Many. One particularly awful case is how at the beginning of ruzi invasion of Ukraine a lot several Russian resistance figures were compromised through Telegram due to it using phone numbers for security which are incredibly insecure and needless to say in control of the government.
