The GB seems to have a bunker mentality, that they are special, and that the world is out to get them, so they tend to keep within their tightly controlled, protective environment. Bottlegate proved that there is some danger outside of the rarified atmosphere of their echo chamber; you never know when a camera might be trained on you, or that someone might recognise you as being something more than plain old "Joe Citizen".
Further, TM3's new address was quickly found and distributed, and (as I understand it) someone drove to his gated community to tell the security guard that TM3's "ass is grass". It's no secret that there is a lot of hostility focused in their direction.
So, are they doubling down on their isolationism, cutting themselves off further from any ordinary encounters with the outside world that they might previously have had? If so, are they right to do so? Has the world become that little bit more dangerous for them?
