I think you haven't looked at the code in question.  Apple only
applies the APSL to code that it writes.  There are a number of
projects that were originally external code, and for those, the
license is whatever it started as.  Since the SMBFS code is a
port of the FreeBSD SMBFS code, the license has been left alone.

As to the reintroduction of bugs, I seriously doubt it, since the
SMBFS follows the FreeBSD changes pretty religiously on its own.
