Installing Zoom on your machine is a mistake. 

Their install process is indistinguishable from malware abdv they have a history of shitting on security for all growth possible. 

And sadly governments abd corporations rewarded them for it. 

I don’t need all the features, just two. 

everything else about discord I hate. 

In my world the biggest advantage of Discord is the Availability on consoles allowing voice chat for crossplay. For all I know none of the alternatives you mentioned is available for consoles. I know there are people connecting their PS/XBox audio output with a computer running TeamSpeak to receive VoiceChat and in Game Sound from the same system but this is not a usable solution for most people.

Look at Teamspeak 6. You're behind on the times
