Linus Torvalds is evidence that a good PM/IT manager is worth a lot.
There aren't a lot of people that can make or lead a team to make world class products, but the number of marketing mangers who are exceptional enough to have significant impact on your company aren't that many either.
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).
