Yeah, I think Hanlon's Razor was intended to apply to individuals, not organizations. Often the "stupidity" of an organization is a shield for malice or greed.
Organizations are made up of people. When you have 5000 people making small decisions with 0.1% possibility of being wrong, if have 40% of chance having at least one mistake over 5000 decisions.
People are not independent coin tosses. They coordinate, manage, overrule, scheme, discuss, and process information in strategic ways that render these kinds of extremely simplified models impossible.
