A Red Hat page about RMS Linux
(https://store.redhat.com/commerce/store.cgi?page=/more_rms_intel.html)
says:


"To qualify as an exclusively Free Software product as defined by the FSF, this
four CD set does not contain Netscape, Qt, KDE, and several additional
non-open-source packages which are available in other Linux products."


Qt isn't (L)GPL (as in "defined by the FSF") and KDE won't run w/o it, but
KDE and Qt _are_ OpenSource.  I see their point, but perhaps they should be a
little more careful with their wording.
