That sounds... horrifying.
It is not a mistake. It is a mechanic they are designing for more...roleplay elements actually. When you are in your house, you are going to get to talk to other's that are in their houses. It will bring the community together more than you think. It's going to be a great way to get together, plan things, invite people over and just talk. It will go better than you think, don't worry TUXs!
When I'm in my house, the very last thing I want to do is talk to everyone else who is also in their house which is not my house. I'm sure we'll be able to turn that channel off. But it's still an odd mechanic that seems like it would fracture the player-base's ability to communicate. Fleet vs. Planet is already sort of ugh. Then split them again into stronghold? Meh.
