How you can compare Telegram features and ease of use with Bitchat? Same for whitenoise. It's very hard to teach people how to use them. They lack features and most people prefer smooth UI and experience instead of a just working (?) app that nobody use. Most of them use TG channels as source of news, buying VPNs, online shop, sharing daily life and more. It lets them to have a full control over permission levels like who see what, and more. It's a universe of features, in a super simple UI that Iranian people are familiar with and using it for over 10 years now. Also Signal and other similar apps are not that much used. People hate WhatsApp here for example.
