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.
Collaborating with Xitter is not the most distasteful thing Telegram has done. Its marketing model has been to consistently lie to people about being encrypted when that’s only true in very limited cases. It has also catered to criminals by attempting to make it difficult to comply with legal demands for information, while holding that information for its own purposes.
Signal, on the other hand is always encrypted and does its best to hold as little information about users as possible.
What is there to learn? Every popular messaging app has pretty much the same UI.
