That is because iMessage has the same function as the night men in the Eagles song Hotel California:

   "Relax,” said the night man, “We are programmed to receive
   You can check out any time you like but you can never leave"

Somehow fittingly that song is about the excesses of American culture ... also about the uneasy balance between art and commerce [1] according to one of its authors, Don Henley while also having been interpreted as being all about American decadence and burnout, too much money, corruption, drugs and arrogance; too little humility and heart and a metaphor for hedonism, self-destruction, and greed ....
