Two of the three resignations were planned beforehand and were not related to the CEO choice (see the update at the bottom of http://arstechnica.com/business/2014/03/three-mozilla-board-...).
Thanks for the clarification, haven't been following this very closely and didn't read Mozilla's statement in response (it wasn't very prompt.)

Nevertheless, I'd suggest that being able to walk and chew gum is something a CEO needs.
Evidence suggests that they've been spending months fighting a battle pertaining to picking an insider as CEO, which ultimately caused three members to resign from the Moz Co. board.
Which explains why they were so unprepared for anything else.
e: Bogus theory by Ars and WSJ, Mozilla issued a statement that the shake-up of board members was planned well in advance amongst themselves for various reasons.
