What about them? There’s no reason to believe oxidation defects during manufacture is a cause of those failures. This is a complex problem with several interacting causes and failure modes, and assuming that oxidation is the cause of all of them (that there exist chips not during the oxidation defect window that failed, therefore the oxidation defect window must be larger) is circular reasoning.
