One could look at this story case-by-case and what happened to the affected individuals. Did the device directly lead them to harm? Of the wide coverage of this story, I see no testimonials from affected people.
We're left with the statistical perspective. I don't see the math supporting this story. I expect that as many or more people would have been harmed by diabetes during the time period without this bug.
I think it is more harmful to perpetuate the lack of context or analysis that brings crowds to look at statistical noise and agree that something must be done about it.
