None of this has to do with the Mach part of XNU. There are genuine bugs there (everyone hates the memory code for example) but again that is completely irrelevant here.

You may be thinking of Andrew S. Tanenbaum, who created MINIX, and was famously blasted by Linus for not having industry experience.
Mach was written by guys who ended leading Microsoft Reaearch and software development at Apple.
