Uh ? What are you talking about ? Why should I ever expect any  
change I would make beeing rolled back into anything under any  
license ?

Brutal answer:

The first three letters of GNUstep are 'GNU'. All copyright on  
GNUstep code is assigned to the FSF. So, if FSF says 'avoid APSL  
code', I read that as 'avoid APSL code'. It doesn't matter if it is  
political, or if rms flipped a coin. The result is 'avoid APSL code'.

You original, question was:

> Can GNUStep use Apple's "Core Foundation"?

As CF is APSL, GNUstep is FSF, and FSF said 'avoid APSL code', I  
think that the answer is NO.

Less brutal answer:

As you may discover by reading  
<http://www.gnu.org/philosophy/apsl.html> there is still one big  
limitation imposed by the APSL license that make impractical to take  
code from it for use in the GNU project.
