It did though. That Theranos was at heart a complete scam doesn't take away from the quality of its marketing and promotion. If anything, it shows how exceptional they can be, in elevating even a mostly worthless "product" to media attention until the lies become impossible to hide.
I think this is the wrong takeaway. I understand your point, but ultimately the company failed and there is a possibility Elizabeth Holmes will go to jail. There was no financial payout. Doubling down on bullshit just leads to a worse reckoning (at least in a world with accountability, and sadly that's not always the case).
