This would be like calling all of email "GMail" or "Outlook". Sure, some people do say that -- but it's still inaccurate.
> How does wire compare to matrix?
Matrix has most of the same features, but also supports groups much better than Signal-based protocols (a group-wide key is used an regenerated frequently, which amortises the cost of all the peer-to-peer messages required for Axolotl). It's also federated -- which means you can also self-host your own homeserver (very similar to email, but even easier). And Matrix has native support for bridges to other chat systems, allowing you to reduce siloing between chat platforms (you can talk to Slack, IRC, and Matrix users in a single Matrix room completely seamlessly). As far as I know, Wire doesn't do any of those things.
I also think the newest features Matrix has for key exchange (both the emoji-based verification and the new device cross-signing features) are objectively the most intuitive and easy-to-use when compared to any other E2EE chat system. Yes, even better than Signal's UX for key exchange.
Yes but I was referring to the clients.
