I disagree with this sentiment. After reading Bad Blood as well, I must say that nobody at the company deserves much punishment. It's Theranos's investors and Theranos's business partners that are mostly at fault. They didn't do their due diligence and simply assumed (hoped) that the technology worked. They were too concerned about missing out on the "big one", which clouded their judgement.
No patients were harmed. The only losers in this are the investors that invested in Theranos. Given that they blindly trusted the pitch, without verifying that the technology worked, that makes them very bad and unskilled investors.
Unskilled investors losing a lot of money is, in fact, a very good thing for the Silicon Valley ecosystem. It's how bad influencers are flushed out of the system.
