Yes, this is roughly my take. The cheating is bad and should not be condoned. That said, it looks like a serious indictment of the interview process if someone couldn't pass it without cheating and but then goes on to excel at the actual job. It means the interview filter process is selecting the wrong things and needs to be scrapped and replaced*. Of course, what to replace it with is a huge question on its own too. *In fairness an alternative explanation is that the promotion process is also broken and rewarding the wrong things.
