I seem to remember a software piracy case from a number of years back. The
case was settled by Apple showing that their code had been copied by the
copyright "easteregg" hidden in the roms. Made for a quick and effective
demonstration in court. (The story may be apocryphal, but it makes for an
example as to how such things do have a (supposed) valid use in protecting
code from being snagged by other companies.)
