As it was explained in the bake-off: the disclaimer (second paragraph in the 
license text shown in is all enclosed in 
square brackets ("[...]"), and therefore was considered optional. The same 
happens with some individual words ("and", "that", etc.) of the first paragraph.

Therefore some text matching only the first paragraph can definitely match the 
complete license. That was the case found.

Yes, once this is correctly rendered in a template, this would be much more
