Earlier quoted context omitted.
I lot of legitimate businesses fall into that category. Also illegitimate businesss. Theranos was definitely illegitimate (and had the characteristic of little fish investors trying to sell to bigger fish), but it would be a pretty severe category error to call it a ponzi scheme.
I dont agree, many others consider what she did no different than a ponzi scheme. It's not just me and the patent commenter: "Holmes duped just about everyone about the efficacy of Edison. For 12 years, she essentially ran a Ponzi scheme by attracting millions of dollars from primarily venture capitalists that saw it as a unique opportunity to cash in on the boom in Silicon Valley." https://www.ethicssage.com/2022/01…
I can interpret this in many different ways. Maybe they mean "no different than" in the sense of "no better than", ie.: as a moral or value judgment.
But if I interpret the words literally, then these people are just wrong. Theranos was a terrible waste of capital, and there was plenty of fraud involved, but it was not a Ponzi.
