Well, the thing is, at least based on the article, Burton- the accused groomer/pedophile/sexual assaulter- does not work for Google. If he did, I'm all for firing him right into the Sun. The article makes no allegations that any of the people employed by Google participated in or covered up the sexual assaults, just that they were members of a organization led by a sexual assaulter. I just get a little antsy about firing people who are not themselves accused of sexual assault- or even accused of direct knowledge and coverup of the assaults, because I don't see a clear and convenient way to differentiate the Fellowship of Friends from the Southern Baptist Convention from the Boy Scouts of America, (unless you want to ban all "cults" and think that can stick).
I don't know more about the FoF than what's in the article, but I've done some reading about a similar sexual assault ridden cult, NXIUM, and their the hierarchy was such that clearly some people were assaulting, and some were assaulted (and some were on both sides at different points), and I would want to be damn sure that I was firing people on the assaulting side but not the people on the assaulted side of the line, and for the people who were both... I dunno, really hard question.
