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.
IIRC Signal stated that they can collect IPs of some users if asked by a judge but that’s about it (not retroactively). Which imo also further proves that they actually value privacy without using it as an excuse to make money from people doing truly evil shit
