I think Mumble as an OSS voice chat project has had its success and has brought some net positives to the ecosystem since its inception. But nowadays, especially since pandemic times, the focus of the technology has moved and newer systems are in place which bring very powerful possibilities to the audio/video conference field. WebRTC has seen an incredible push and if you only wanted Mumble for its open-sourceness and its use of the Opus codec for low latency, you might be better off by joining a Jitsi room with your friends and enjoying the immense effort that the web browser already brings in matter of echo cancellation and other shenanigans related to conferencing apps, plus the better UI that these kind of projects offer for end users (Mumble's bad UI is a common topic). On the other hand there is Discord, but it plays in a different league because it is closed-source, VC-backed, and uses some advanced technology like AI-based noise cancelling.
