Always amusing when a bunch of lawyers over-react to something, supposedly on their client's behalf, and then when the client finds out about it, they have to talk the lawyers out of it and tell them to chill. I've always wondered if lawyers are born without a sense of humor or if they lose it during one of the semesters of law school.
You appear to have misunderstood what happened. It was her management team that thought it was in bad taste. They then got the lawyers to draft a letter. The lawyers weren't acting "supposedly on their clients behalf", they were doing exactly what their clients asked them to do - which is their job. In this case, it was the management team that was acting "supposedly on their clients behalf" and who needed to chill out.
