If the goal was to give the magazine some relevancy beyond its shrinking, aging, audience, I don't think that Foer and Wiesetlier were the right people for the job.

Sure, just as if he can't sell his particular ideas to his staff, its there prerogative to leave. Of course, if he has spent two years "cultivating" them and then is surprised when there is an exodus -- even after having been specifically told that that would be the result if the editor that he replaced left -- then clearly his work at "cultivating" his staff is pretty good.
And if he has that little understanding of what motivates a fairly small group of people he actively interacted with for an extended period of time, one might also wonder how good of a grasp he has of what motivates the audience he is seeking with TNR.
If Hughes doesn't want to subsidize a money-losing institution with a declining and aging readership, then isn't it his prerogative as an owner to shake things up? He may have gone about it the wrong way, but ultimately wouldn't the public be better off with a TNR that has an ability to support itself and thrive in the future?
