I just don't buy it.
I've been fascinated by this case for a while and have read the John Carryrou book twice, and also seen the documentaries. To me it seems they both know it wouldn't work; they specifically put in place competitors equipment to complete the blood tests that they said that their solution was producing, and then lied to investors and other potential customers about contracts that they had with the US DoD. All of that is pretty much documented.
Also the amount of testimony about how Theranos tried to prevent, and threatened anyone from speaking about "working at Theranos" is also telling.
I get that EH was driven, but I also think she's a bit of a sociopath who (A) really REALLY wanted to be Steve Jobs, (B) Absolutely stage managed her image and voice, and (C) couldn't accept that her idea wouldn't work.
Was she abused? Well, I don't know, but from what I've read most people say that she was a "force of personality" so I very much doubt it.
Did Balwani abuse her, again, no idea - but he does come over as a bit of a self aggrandising twat / liar who probably will get everything he deserves.
