It's possible to look at the behavior of a company over time and infer their internal incentive structure. It's been clear for several versions of MacOS recently that Apple spends much more energy adding features than fixing bugs. It seems obvious that there is no incentive within Apple to fix bugs; the only thing that gets one promoted at Apple must be adding new features -- so bugs (at least in MacOS) don't get fixed.
We already know that Apple makes about 51% of its revenue from iPhone sales. Therefore it's reasonable to assume promotion opportunities are mostly centered around iPhone hardware and hardware, rather than MacOS. Those of us who depend on MacOS are likely screwed unless something at Apple changes.
Having read Showstoppers a few times, I wish Apple had a David Cutler that mows on developers' asses if their code is too buggy.
Kinda all large system projects need someone similar to get things done properly.
