I think it is worth noting that Theranos went after people who investigated them. Used the enormous war chest and high profile backers to crush anyone who challenged the official narrative. How many nascent stories get killed because a broke reporter feels threatened?
How many "journalists" wrote glowing puff pieces about Holmes and Theranos, when they could have simply written about other companies and people instead? Quite a few as I recall.
News begets more news. I am not going to fault a reporter for getting in on the current zeitgeist.
Unless you are comically bad at crime, bad actors will maintain some level of misdirection to conceal their malfeasance. There are only so many hours in a day, there is not time to do a deep dive report on everything that comes across the desk (most of which would match the official narrative). Theranos took years of concentrated effort to expose, with a large amount of risk (real or implied) to those involved.
