The Twitter exec team & board is between a rock and a hard place.
If they take the offer, half the exec team (or the entire exec team) will be axed (Musk already indicated he's not happy with management in the SEC letter [1]).
If they reject the offer, they will be drowning in lawsuits due to not filling their fiduciary duty (getting a good deal for their shareholders [2]).
