The board is getting a lot of crap for being crap. Regardless of your opinion about their goals, their execution was objectively terrible. They were clearly completely detached from their organization. At the very least, they could have made sure their first interim CEO wouldn't instantly try to turn against them.
It's not a contradiction to criticize someone for saying too much sometimes and saying too little another time. The board should be open to insiders and cautious with external communications.
