this strikes me the same way as the story of the guys who figured out where to add armor to bombers during WW2. the places on the plane that had bullet holes after a mission clearly were operational enough to return to base. the places that never had any damage were probably critical, so that's where armor was added.

if a company can make billions with a poor-quality codebase, clearly quality isn't a bottom-line concern.

what is a concern is shipping the damn product.
