It is a correct statement, not really "borderline narcissistic". The board's mission is to help humanity develop safe beneficial AGI. If the board thinks that the company is hindering this mission (e.g. doing unsafe things), then it's the board's duty to stop the company.
Of course, the employees want the company to continue, and weren't told much at this point so it is understandable that they didn't like the statement.
