I am against the name change. If you care why, read on.

GNU has indeed made huge contributions to what's on our machines. As
others have pointed out, so have Qt, GNOME, KDE, X.org, OSS/ALSA, driver
writers, OpenOffice.org, Apache, Eclipse, and many many others under
different licenses.

However culturally, we identify the software we install as "Linux
distributions" and say we run "Linux," even while we are all fully aware
that what actually runs is a large collection of software from many
sources.

IMHO, singling out GNU as *THE* contributor above all others is unhelpful,
too wordy, inconvenient, and confusing.

My two cents,
Chris
