While I am somewhat sympathetic to the board based on what I have read about Altman's behavior pattern (he was allegedly fired from YC for similar reasons of not disclosing conflicts of interest), it is strange to me how thin the board members' resumes are. What notable achievements does Toner have? She's 32 and hasn't really built or run a company.
Another board member is the wife of actor Joseph Gordon Levitt. Same story -- no notable achievements or experience running a business.
A more competent board would have handled things better and may have prevailed in their ouster of the CEO. Here they just got outmaneuvered even though they may have been right in their call.
