Late to the party but...
alternatives?

Revolt/Moat.chat - Discord clone, a shit one too.

TeamSpeak 6 - Just like Discord in ui/ux, self-hostable apparently, BUT read their EULA and Clause... They give EVERYTHING you do to all the companies you don't want! 

Would you rather China, a country you would probably never visit, or the 5-14 eye nations eyeballing your every move?

Self host Matrix/XMPP stuff I guess? Make your own client or actually build the private community *you* want on nostr. The whole point of this protocol rn to me is getting people away from tyranny and showing them something else that's out there. Anything...

But I cannot onboard people to a discord clone that does not exist.

Keep in mind too, every single person that can *do* something about the state of the world... are the teens and 20-somethings. They are ALL on Discord still and Twitch and these centralized platforms. The realization that they are not safe is becoming very apparent to them with RING doorbells cooperating with ICE and US. GOV to be a spy network. 

Just scream wolf if you see a wolf... I would hope that at least one person takes notice.
