The Wikipedia used the GFDL because it was recommended by the FSF.
They used it in its natural way. And then they got burnt.
I fetched those pages, anxious that they might have had a serious
problem, but when I saw the contents I was relieved. They were just
discussing whether they are better off using or not using invariant
sections, and how to use them. Words like "burnt" do not fit the
situation.
