Cruise/Redstone takedown, part 2

Slate says that

Redstone, who recently married a woman half his age, puts great stock in his virility. And in recent years, he has periodically released his excess testosterone by firing good-looking, middle-aged bucks who have gotten too big for their britches. Last month, it was megastar Tom Cruise. Earlier this week, he cashiered Tom Freston, the CEO of Viacom and one of the founders of MTV.

Is Redstone's need to fire younger guys merely rational decision-making by a canny CEO? Or does it reflect some bizarre reverse-Oedipal envy?
