Eric Felten writes in the Wall Street Journal on the National Portrait Gallery-Wikipedia dispute:
"Copyright law exists for a purpose: to make creativity pay. Making accurate photographic copies of paintings is no doubt valuable and involves painstaking work. But it isn’t—and isn’t meant to be—creative. With all the digital assaults on the old copyright verities, the champions of intellectual property can’t afford to waste their energies trying to monopolize images that already properly belong to us all."
