We're only getting one side of the story here: the story of the DOJ, which has its own political interests. And in typical fashion with these highly sensationalized scandals, bullying and shame are deployed to force people into one camp or the other. People are discouraged from finding a middle ground, trying to empathize with both sides, etc. They're told, "X is bad, and Y did X! How can you still act in any reasonable manner toward Y? He must be banished!"
We need to be careful and we need to quit feeding our own to the wolves. We need to back off of our hair-trigger. So far, I know of no documentation that shows clear mens rea on the part of Catmull, and even if that is shown, it doesn't mean all of his contributions should be thrown out the door. That's very simple-minded, silly thinking.
