Element has come a long way, and is now a fully-featured group chat application, with spaces (to group several rooms), numerous bridges so people are not locked in one single tool, and great integrations.

Open source, very powerful. Can be hosted independently on own hardware but also as-a-service. Does the exact same without limiting the user to one service provider or client.
