@nprofile1q... @nprofile1q... Yes DeltaChat is a messenger and XMPP is a protocol.
Why is the advertising towards DeltaChat so obsessed with protocols? Just say "DeltaChat is better than Conversations, because it provides a consistent UX across platforms including iOS." This would render your point much easier to understand for everyone and wouldn't require you to badmouth protocols you're relying on yourself.
