“Any sufficiently advanced incompetence is indistinguishable from malice.” - Grey's law

Eh... you never lived in a corrupt state, have you?

"Never attribute stupidity what can be explain as sheer corruption, aka malice"

That thin concrete that doesn't meet requirements, was put there not b/c of stupidity, but because someone lined up their pockets down the line, and the quality assurance people were paid to look the other way.

Hanlon’s razor is obviously nonsensical. Malice is fundamentally stupid and obstinate stupidity rises to the level of malice so the distinction makes no difference.

"Never attribute to stupidity that which is adequately explained by greed" - an alternative formulation of the law of parsimony (aka Occam's razor)

Hanlon's razor is a boundary condition. Over time strategies improve, including malicious ones.
