Also, the executive who said it wasn’t for malfeasance wasn’t himself on the board and appears to be trying to push for Altman’s return. The board themselves has not yet said there was no malfeasance. To the contrary, they said that Altman had not been completely candid with them, which could very well be the last straw of malfeasance in a pattern of malfeasance which in aggregate reaches a sufficient threshold to justify a firing.
I don’t know whether there was or wasn’t malfeasance, but taking that executive’s word for it seems unwise in this polarized PR war.
