I don't want to see Apple hurt (I'm an Apple-guy myself, using Macs, iPhone, iPad and Apple Watch), I want to see them improve. I doubt they start will start caring about QA unless they're forced to.
One absurdly serious and stupid password bug like this can be a honest mistake, but three (that we know of, that were full disclosures) in a few months is negligence that should be criminal if it isn't.
