Halloween Documents n. A pair of Microsoft internal strategy memoranda
   leaked to ESR in late 1998 that confirmed everybody's paranoia about the
   current {Evil Empire}. These documents
   (http://www.opensource.org/halloween/) praised the technical excellence
   of {Linux} and outlined a counterstrategy of attempting to lock in
   customers by "de-commoditizing" Internet protocols and services. They
   were extensively cited on the Internet and in the press and proved so
   embarrassing that Microsoft PR barely said a word in public for six
   months afterwards.
