If they really felt it was so important to have the GNU label on Linux they should have made the Hurd kernel as popular as Linux, or put effort into Hurd before focusing on the tools. Or they should have added a sentence in the GPL that enforces it. (wink wink nod nod there are thousands of packages released under GPL so why continue the whining?) Because they never stop whining (and because there is a "debate" in the first place) proves my point that it's perfectly fine (if not my duty) to continue referring to it as Linux.
