Voice chat is not for everyone, doesent mean it shouldnt be allowed
Every time i play CS:GO i sometimes hear other people speaking and most of the time they are funny things, i laugh, i get entertained and since im a casual player i prefer it than not to have it.
Sometimes there are people that put loud music or troll, guess what i mute them and poof they are out of my game.
Voice chat isnt for everybody, especially autists but who are you to turn off the music for the rest of us? that's why theres a mute button, heck we'l give you an AUTO-MUTE, so that you are in mute by DEFAULT, how great is that?
