You can blame the execs, but the real question is, where was the board of directors who were supposed to provide governance during this time. Ultimately they approved it and you don't hear anyone calling for their ousting.
I'm not going to bat for the executives at all, but given the opportunity to take $22m off the table ala Dan Wright, why wouldn't you? Shame on him but he'll wipe his tears with hundred dollar bills. Why did the Board approve this sale — that's the real question.
