I'll echo what most others say here: stop using discord and everything microsoft.
And maybe also reconsider if modern gaming is a worthwhile passtime.
Look, I love a good game as much as the next person. But with everything that is coming to light lately I can't shake the feeling that I want as little digital backdoors for their tentacles around. Because they are harvesting data all over the place.
I hear you (figuratively speaking, because I don't use voice chat for gaming). My answer would be to quit.
Now I know that's a bit extreme for some. We all have our things that we're willing to give up or not. (Outside of gaming also).
I for example have a hard time getting people of whatsapp (pos meta spyware that it is). But keep at it, some changes take time. However, as extremer this world gets, the more people will open their eyes and take steps.
