I had an extended exchange with an Uber employee the other day, in which he steadfastly refused to believe that Uber was going after Fowler after the initial reports of this. Despite countless examples of this kind of behavior in the past, he kept insisting that everything was only "alleged" or "unverified." I'm not sure what kind of cargo cult they have going on over there, but it sure is effective at getting people…
They don't want to believe that an entity they identify with is a bad (ethical, political) actor. They see themselves as good (and maybe they are), and so this thing that they base their identity on must also be good (and in some ways, maybe even most, it could be). Criticism of the entity becomes criticism against the self, which they cannot help but deny because it destroys their own self-image.
