Never attribute to maliciousness what can be better attributed to stupidity. I've worked with managers who simply couldn't comprehend that a particular issue was a problem for the engineering department. No amount of examples, demonstrations, or complaints helped. It wasn't an issue for them, so the issue didn't exist. Their story changed later when they ran into the issue. It was now a problem that had to be fixed immediately. I would explain very slowly that yes, this was a problem. And that they had been made aware of it months ago. And that they had opposed fixes to the problem. The response, of course, was blank incomprehension. They just couldn't understand that they were incapable of understanding something. Needless to say, I don't work with those kind of people any more.
