I’ll speculate why people dont talk. Talking invites targeting, which often leads to even more aggressive talk. Players get trained to just say nothing and keep their head down. Engaging in chat tends to lead to a spiral of just offensive taunts eventually. Its almost an internet law at this point. When you dont know the other people, the more casual players will preemptively keep their guard up. The more die hard… well… their filter is not so circumspect…
