My complaint was that the WMF was (and still is) copying and distributing my copyrighted content in a manner other than that expressly provided under any license I have granted them.
I doubt it. You are probably considering the wrong part of the GFDL with regards to what they are doing. Suffice to say the foundation isn't actually required to credit you in any way shape or form with regards to the dumps (since they are effectively verbatim copying and since there are no cover texts section 3 doesn't place any significant further requirements).
You may not like this but that would be inconsistent with your claims to prefer the GFDL over CC-BY-SA 3.0.
