It's not as alarming if we just reframe it. Apple's software is written by developers, like many HN readers, and they follow similar interal processes. There is nothing inherent about having a large market cap that makes everyone involved superhuman. Some issues always slip through the cracks.
I'm surprised to see this comment on HN where many readers see how the sausage is made. There's no secret sauce, no matter how far up in FAANG/MANGA you get.
