Not sure what you mean by "won't detail". Do you mean "won't include in the list"? Since you've tried to list all the possible speculative causes of this sort of debacle, without committing to any of them... it would surely be odd to omit one because, like the others, it's speculation. But I'm not sure what else you could mean, since no elaboration of the concept is required.
Granted, I've raised an especially unpleasant possibility (as no more than that), especially for consideration going forward; but fraud from other causes is also unpleasant and has to be considered despite being unpleasant and, according to the article, not necessarily an act of commission. To quote: "But the fact that Theranos was a gigantic fraud doesn't quite mean that it committed fraud." You've considered it, nonetheless, and I think that's reasonable - as speculation.
