THERE IS NO STORY HERE CHAPS! Talking with the ground crew it was not even a reportable incident (per Mr. Falcon)
As an MD-11 Captain, I'd want to know the details of a winglet striking the ground, lest it happen to me. Isn't that a tenet of professionalism? Now if it was due to the ground crew, that's another story, but damage has to be written up and repaired. 'Nuff said.
