Copyright is not license.
Materials can be *licensed* under the GPL, and therefore freely copied,
even when copyrighted. In fact, the entire basis of the GPL, as I
understand it (IANAL etc. etc.) is copyright law -- someone has to hold a
copyright on the material in order to have legal grounds for applying the
GPL. If no one holds a copyright, then the material is in the public
domain and the GPL is neither necessary nor applicable.
It is true that in many cases the copyright of GPL'd material is assigned
to the FSF or some similar entity, but that is not a necessary condition
of licensing it under the GPL.
*IF* there were a statement somewhere that explicitly *excludes* these
images or other selected parts of CentOS from the terms of the GPL, then
you might have grounds for complaint, but the statement that they are
copyrighted does not AFAIK constitute such an exclusion.
The effect of the copyright is that you cannot separate the CentOS logos
from the rest of the sources and use them, independently, for some other
purpose, without permission from Definitive Software Ltd. The effect of
the GPL is that you can copy and distribute CentOS as a whole, even though
it includes the copyrighted images. Do you see the distinction?
(Again, I am not a lawyer, and the GPL has all sorts of other effects that
might be construed to make it possible to re-use the logos.)
