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.
