Wow, the ultimate apologist. Imagine if the people in charge of building cars had that attitude.... of course the cars randomly crash and kill people, they are much more complex than they were 10-15 years ago.
My friend, I am a software engineer, and I can assure you that Apple's attitude to quality control is utter rubbish. I simply can't believe how careless they are. If I were Tim Cook, I would fire Craig Federighi in an instant, and completely clean out the software team management, and then go about hiring an actual competent team.
