(It wouldn't surprise me if we eventually get a film adaptation... but those are always worse if you read the book.)
The reporter, John Carreyrou, also caught backfire from Theranos. Especially his sources whom he did try to protect but were stalked by private investigators & lawyers.
Given that Theranos didn't have a product it is only good news that they're finally dissolving. Holmes and Balwani ruled with tyranny and compartmentalisation which created a toxic work environment, but that does not mean all the employees were ignorant or stupid or into the scam; many of the employees were highly skilled and intelligent. Those who did know they didn't have a product (or that it was some dirty hack based on a different product) were manipulated by Holmes and Balwani.
I saw someone mention psychopath. I'm unsure what exactly these two people are. Sociopath, psychopath, narcissist, whatever it is; it isn't pretty.
When I read the book I was regularly reminded by Brian Krebs' "Sources: Security Firm Norse Corp. Imploding" [1]. They also had no real product and used compartmentalisation. Also well written (though way briefer).
