Banning telegram isn't the solution for this problem but I am not surprised if they even think about the complete ban, stupid but very much possible. Eventually they have to ban every messaging app and develop an app that is completely controlled by Indian government.

Anyway, here is the alternative if that happens -
BitList.co - Bitcointalk Notification BOT [SimpleX], just same as telegram but even more privacy focused while being less popular so government might not even consider banning it.
Banning telegram is still fine but developing a messaging app controlled by the government ?
Lol, even if the government will consider creating such an app, why would anybody even install that app ?
It's not like the government can force us to install the app, afterall its just used for messaging.
