> You can do whatever you want using Whatsapp (it has a proven solid e2e encryption), the key difference to Telegram is it requires a phone number to use which instantly reveals your real identity to any snoop, snitch or government mole.
Both Telegram and WhatsApp required a phone number last I checked, but you can install Telegram on a Desktop using a dumb phone for activation, you don't need to run the app.
> If it were that easy to influence Whatsapp, India would not have a real problem with Whatsapp-mobilized lynching mobs.
India has no jurisdiction over WhatsApp. They can ask Facebook nicely, but that's about it.
To stop communication you don't need to read WhatsApp-chats. You just disable the accounts that you want silenced. And you can't do that if you don't have control over the service (hence Western extremists use of Telegram).
If you're Russian and you want to talk about how free yourself of Putin, use WhatsApp or Signal, that is: an American provider. If you're American (or living in an American province) and you want to talk about how to free yourself of Washington, you use Telegram (or a Chinese messenger). Even if none of them can ever read your chats, they can a) use the meta data and b) disable your ability to communicate.
This also applies if you're a common criminal: US cops will have a much easier time getting meta data on your communication from WhatsApp than from Telegram. It's generally a good idea to know your threat model. Unless you're a Russian Oligarch or Ex-FSB, the FSB is not your problem. But your local domestic intelligence service may be, if you ever step out of line.
