Wouldn't this open him up to blackmail and espionage? The people he cheated with whether they exploited it or not had kompromat on him. Not only that but the new allegations show he has a pattern of acting a way that would let people get kompromat on him, and investors were probably not previously pricing in that the CEO himself was a huge insider risk, and now that the cat's out of the bag, they are. Even if he leaves now that wouldn't undo one of his affair partners stealing proprietary info.
