I dont see anyone telling him to use anything else, just people stating their experience...which practical experience shows that just using a different grade of oil does not guarantee death to the engine. I can show you a fleet of30-40 trucks with the 5.4, most of which have had 15-40 their entire life, and the fleet has had very few engine failures, while all of the trucks are ran for 200-300k miles of hard use (abuse), overloaded, lots of start up/shutdown...either way, its his choice what he wants to run for oil, so why would you take it so seriously...oh, I must have forgotten how serious the business of teh internetz is...
