Apps like Signal and Telegram use an open-source peer-to-peer WebRTC solution for voice and video calls.
Why don’t they continue using a peer-to-peer solution for text messaging as well? Shouldn’t it be simpler?
The reason is that, for voice and video calls, both people are online at the same time, whereas for text messaging, users may not be online simultaneously.
Therefore, a constantly online relay is needed to temporarily store messages.
