If we report a segfault Apple will probably think we are to blame. 99.9 %
of bug reports come from idiots, and those who screen bug reports are
basically payed to hit the ignore button. Indeed, good luck on reporting
it.
I've reported bugs to Apple and seen them fixed in major releases of the operating system (though not necessarily minor releases). Unless things have changed considerably since my last bug report, I don't think it's fair to characterize their quality assurance team this way, particularly without evidence to back up your point.
