Rudin appears to have broken really the *only* enforceable governor on an execs conduct and trajectory, which is to antagonize the gatekeepers—plural. From media reports it appears Weinstein departed from his original policy, which was to lavish his staff in exchange for silence.
Every six months to eight months, there are attempts inside Condé to "change" or "nudge" Ms. Wintour. If you haven't noticed, these efforts never succeed and I can assure you that they never will. It's more likely the CN union push will succeed, and it may if she blesses it.
P4/Petraeus is obviously a unique case study, in that the trajectory was at times uncertain but the prestige was assured; a personal choice, of bail or buckle down. Some of that camp now refer to him as P5, and bailed. Others—strategically—did not. Choose your own adventure.
When there is a board empowered and willing to govern both the conduct and the profile of the CxO—these are four separate things, you have to lock down all four or the board is marginalized—you can impose from on high, or even push the exec out yourselves. But buy-in is required.
