One of the comments here had a good possible explanation which is that sharing the details might expose the board to liability since they now would have admitted that they know the details of some illicit thing Sam did, for which a lawsuit is coming.

For example, one scenario someone in a different thread conjectured is that Sam was secretly green-lighting the intentional (rather than incidental) collection of large amounts of copyrighted training data, exposing the firm to a great risk of a lawsuit from the media industry.

If he hid this from the board, “not being candid” would be the reason for his firing, but if the board admits that they know the details of the malfeasance, they could become entangled in the litigation.
