Telegram has always felt like the catch-up of the messenger apps. I don't know a single person who uses it.
I don't get this. I'm in the EU and nearly everybody I know has Telegram. Telegram has a huge advantage versus WhatsApp: it's not Meta. Then the Telegram UI is really excellent. When you tell people all your friends and family are using it and that's it's not from Facebook, they usually install it on the spot. Then they're hooked.
Except the government, as reported in the news.
Actually the only time I used it it's because I needed to chat with a Russian SaaS personnel.
