I respectfully disagree that the shrug should be read as indifference to the issues going on. I think the rest of his apology, regardless of whether it was sufficient or not, shows that he is taking it seriously.

That's not at all to question your decision to be done with LMG. Anyone who chooses that in this situation is completely justified, IMHO. Madison's accusations especially are very troubling, and I hope they deal with it thoroughly, and tell us what they did after it's taken effect. That sort of behavior is completely unacceptable and if it means that Linus needs to go, then Linus needs to go.
