i Think disabling the chat on an all in is fine, because if it wasnt disabled people would be able to influence other players by making comments and such like. However i believe that the chat should be allowed for the all-in player and the one player left who is deciding to call or not. With it only being these two players who would be allowed to chat the all-in player would be able to try to smack talk to try to induce a call, but only when its two players remaining, but the other players wont be able to call. But in my opinion not having it period is just fine, not really necessary for players to chatting when someone is all in to induce other players decisions
