With that logic why should anyone ever seek a remedy to a failure in judgement?
Intel has had excellent ARM chips in the past and has sold them off. They are too married ideologically to X86, just like Microsoft was too infatuated with Win32 as an API. Intel selling ARM is I think to them a signal of defeat in loss rather than a focus on the customers needs. I think AMD is being rather mature in making a server ARM part.
You can't change the past, so what'd be the point of getting furious at the management?
