This has the feel of the CEO rounding up as many patsies as he can find to scapegoat in order to placate the investors.
No doubt the culture there is rotten to the core, the rumors of the horrible work environment and harassment are widely known, however, I predict you won't see too many of the exec team having to leave. It'll be all low level expendable IC's that the CEO won't have to encounter at the country club after the sacking.
