I see "has decided to pursue other opportunities", as, they have left before they were sacked for something usually so bad that the company will never speak about it publicly.
e.g. Mark Hurd @ HP hiring a softcore porn actress and using the company jet for far far far far far far too many personal flights around the globe, and too many sexual harassment incidents. The board, which he hand picked, allowed him to leave " to pursue other opportunities" with a golden parachute studded with diamonds, emeralds, sapphires and rubies (somewhere between $30 to $40 million).
