Where did you get that info from? I'm a CM (who, for the record, stays with their friends when I sign them in), and I have heard NOTHING of this "rash of CMs" who have been fired.
That is, other than the story that has circulated every single "high season" since I got to Disney over 15 years ago. Every single spring break, summer and Christmas, there are rumors and stories that large numbers of CMs have been fired for Main Entrance pass misuse. I don't doubt that people get reprimanded and fired for misusing their passes, but I doubt that there has been "a rash of CM firings" lately. That many people fired for the same thing would have made news somewhere.
