“GNOME is not an independent software project; it is a part of the GNU system. This means GNOME does not exist just for its own success. It has a purpose: to provide the GNU system with a desktop. So while we should try to make GNOME successful (all else being equal), that’s not the highest goal of the work on GNOME. […] If, on the other hand, GNOME and the rest of the GNU system are widely used, but mainly in combination with proprietary software, they will have succeeded only part-way, and a big task will remain ahead of us.” Read the rest of the answers, and also have a read to the issue that was raised a month ago between RMS and some of the GNOME members.
