From http://meta.ath0.com/2012/02/05/apples-great-gpl-purge/, with access forbidden right now:

Apple obligingly allows you to browse and download the open source software they use in OS X. Since they have listings for each version of OS X, I decided to take a look at how much software they were using that was only available under the GNU public license. The results are illuminating:

10.5: 47 GPL-licensed packages.
10.6: 44 GPL-licensed packages.
10.7: 29 GPL-licensed packages.

This clearly supports the idea that Apple is aggressively trying to remove all GPL-licensed software from OS X. While the removal of Samba and GCC got some attention, the numbers show that there’s a more general purging going on.
