The FSF does maintain this list to draw attention to various projects it considers critical to achieve parity with proprietary platforms. FSF put OpenOffice.org on the list, despite that it is open source itself. However, it is based on Java and depends on features that are not available in the free Gnu implementation of Java.
With the recent release of OpenOffice.org 2.0 the goal has apparently been achieved to eliminate all the quirks, that prevented OpenOffice.org to compile on GCJ. One caveat, this build is not the fasted in the world and rather not usable. But the FSF claims the principle goal to be achieved and hopes that future GCJ implementations will take care of reasonable performance.
