DFSG: Debian Free Software guidelines.
The OSI definition is the same as Debian's
Open Source and Free Software are two entirely different things.
See the contradiction? In fact, if you'd done your homework a bit more you'd see that the DFSG are not the same as the OSI rules. Debian's rules are stricter, which is why the Apple license doesn't qualify.
And please lose the condescending attitude. It dosen't suit you.
