I have always maintained that Wikipedia editors should
appointing WMF as their non-exclusive agent whenever they edit.
That's as may be, but the fact of the matter is that the WMF is *not*
a non-exclusive agent. In fact, the WMF didn't even exist when many of
the edits were made. It is far too late to change the way copyright of
Wikipedia content works. It is released under the GDFL and only the
GDFL and will only ever be released under the GDFL. Accept it.
