Because the devices involved are mobiles? What else would you use.

Almost all end–user devices are mobiles. When everyone had a desktop you made a desktop app. When everyone has a mobile you use a mobile app. When everyone has brain implants you'll make a brain implant app.

That's if you want to reach the most people. If you want to reach the much smaller community of people who oppose the current thing, you'll make a different type of app.

As opposed to what?

Tbh, anything that is not a proprietary closed garden. Why access to the clubs/interest groups now requires to compromise the privacy?

Wait, you're saying that using Signal or Telegram is compromising privacy?

I'm really curious what you're hoping for?

>Wait, you're saying that using Signal or Telegram is compromising privacy?

How come after all these years even people here still don't know telegram by default has no end to end encryption at all making it worse than facebooks WhatsApp? At this point it deserves to be called telegram distortion field.

For starters, not sending a notification "he is now using this app!" to everyone who has my phone number.
