This message is so clearly directed at the internal audience of Moz to try and frame his failures to rise as the CEO from a founder and garner internal support. If I'm Sahah, I'm clearly annoyed at this and see it as part of the reason he lost the job in the first place. All the drama he presents you don't see coming from any other CEO or corner office in tech. The real 'honesty' is clearly read between the lines that he doesn't want Sarah to be the CEO and wishes he were still in the position despite his former and current failings. Companies reach a tipping point at which time they need an operator instead of a perpetrator of drama following bad results.
