Yup. It’s dead.

For me it’s as long as it’s not Discord.

Stoat.chat seems to be a more likely alternative. I love matrix, but I don’t think it can replace Discord. Not yet.

Some options:

Use Steam groups, which has almost all the same core capabilities (voice chat, push to talk, image and other sharing, etc.)

Create a teamspeak server if you have the know-how.

Create or join a TeamSpeak server.

Whatever they find is inadmissible, if there truly wasn’t a warrant.
