The board aren't going to be able to hire someone who is both an effective and experienced CEO and willing to completely ignore their misconduct. If it turns out the actions of the board weren't reasonable, it's hard to see how it can survive in it's current form.
Emmet Shear presumably had very little to do with the prior events, but if he's going to salvage the company, he needs to control the narrative around the governance. That means either publicly justifying the boards actions or changing the board.
