It’s tangential, but Mumble is still good for voice only chat. Rarely do we find video to be useful or necessary with a lot of collaborative tools showing multiple cursors per users & programs like Upterm that allow sharing a terminal session.

The generation where I did not have adult responsibilities to prioritize

XMPP + OMEMO & Mumble for chat, offline maps from OSM, self-hosted feed aggregator

NixOS, OpenWRT, LineageOS for microG, but would like to remove Android from my line up.
