I suspect it’s not that people can’t do the work and more that Apple’s silos mean their already employed engineers are not allowed to try or even talk about it.
For things like Final Cut/iMovie with lots of video/audio/misc tracks, it was trivial to saturate the disk with dumb seeks when reading otherwise linear data streams due to a lack of knobs.
I wonder if it was possibly not that you compared the kernels but rather how you chose to express the comparison. For example this bit makes me think you possibly expressed your opinion combatively:
> a dogshit IO scheduler
Perhaps you were more polite in your day-to-day, I don't know. But your language here makes me wonder.

So I'm sorry I offended you with my salty language but the evidence suggests I'm far from the only one that went ignored at Apple.
You didn't.
the way you are responding to some one who asked you a pretty mild question (assuming they were personally offended rather than asking about a potential communication issue) suggests there is some validity here.
Sure the phrasing was gentle, but the actual statement was quite offensive, presumptuous, and prudish.
Which is probably the root cause of the GUI civil war happening between all desktop frameworks.
Inside Windows NT from Microsoft Press
First, Candy Crush was never preinstalled. A link to purchase it in the Microsoft store was preinstalled, and it took all of two clicks to get rid of it if you wanted to.
Second, preinstalling that link reduced malware infections of windows systems by a visible percentage worldwide.
Microsoft has a duty to protect users who need it. Finding a compromise where the worst case for other users is that they need to click twice is pretty good.
Why? Because people would pirate it? Or Just download virus laden games in general?
Also as an aside, that link _kept coming back_ on my laptop (but not my desktop oddly).

Unfortunately, Microsoft didn't exactly treat him kindly [1] in the end. And to add insult to injury, his blog was completely wiped. There are some archives around, but I haven't seen one that retained the images, which often makes the posts incomprehensible, unfortunately.
