We'd probably need to make some drastic changes to the game where there are text chats, but people are using voice chat...
Why are they assuming only under 30s want this? I've been an online gamer for 20 years and dont remember a tiem where voice chat hasnt been possible in some form.
Until recently, teampseak or discord have filled that gap, however with Discord now begging for cash just to make a simple voice call understandable in call quality we really need to move away from these apps.
