Apple's number is finally up - and why we've gone our separate ways while I continue to use macOS

All companies basically treat defects as a numbers game: if it’s more cost effective to ignore a problem than to repair it, they will ignore it. At least it was only your money and not your life. The 1973 Ford Pinto had a design defect that made the gas tank explode if the car was rear-ended, even at low speeds. Ford prepared a memo arguing that whereas the $11 repair/improvement needed to eliminate the problem would cost a total of $137 million (about $850 million today), the 180 burn deaths and 180 serious injuries that would result from doing nothing would have a “social cost” of only $50 million.
