It is not obvious because a viral license assumes that
all other content
will be contiminated with the same license. Hence when GFDL only is
incompatlible with our projects this material cannot be used in our
projects. This defeats the objective of Commons.
Mere being on the same server (i.e. on Commons) does not trigger the
virality of the license. And since we have been combining GFDL text
with CC-BY-SA-only pictures (et al.) in our projects for many years, I
don’t think we should now hardly switch to strong-copyleft beliefs and
ban all GFDL.
This should be obvious and hence it does follow that
it is correct to
indicate that GFDL only material is not suitable.
GFDL is a free culture license, copyleft (license virality) is a
completely acceptable condition for Commons.
