Clearly people porting OS's *do*not*want*Apple*source*code*; if
they did, they'd be writing apps on Apple's existing OS or writing
their OS as a hosted OS using "Apple's source code" which has been
translated into object code in the system ROMs.

Equally clearly, you have been so busy wearing your "Mac advocate"
hat that you have failed to followup on the URL's posted here as
references.  So here is the official word on the missing information,
downloaded for you rather than included by reference, since you
appear unable to follow references:
