So, as it turns out TeamSay is gone, and just broadcasts to everyone.
Let me tell you why this is a terrible idea: Because people who don't know it is gone will end up broadcasting important tactical information by accident, since nobody had actually mentioned this change.
Furthermore, there is literally no logically-sound reason to have removed it.
So what should happen is either TeamSay should simply not broadcast to anyone at all, or... work the way it was working before? Like, literally, if it ain't broken, don't fix it. That is all.
