Matrix is a protocol. Element is a reference app built on top of that protocol, and Element looks like Slack/Discord.

Other apps built on Matrix do not look like Slack, e.g. Fluffychat, which looks very similar to Signal.

But don't you still have the same server paradigm on Fluffychat as you do with Slack/Discord? That's very much not like Signal/WhatsApp.
