You do not fine Home Depot if a suspension bridge fails because the builder decided to go there and buy the cheapest rivets to hold up their suspension bridge instead of sourcing components that meet the design specifications. You fine the bridge builder for using components unfit for purpose. For that matter, even considering to use components that unfit for purpose is inconceivable in most professions. Only in software do people use systems with no specifications, no guarantees, and where even the component makers did not intend or design them to be load bearing.
