The wheels of the law grind slowly. Look at Elizabeth Holmes. The WSJ article that started her downfall came out in 2015. And she's still walking around free (for now).
The FTX dam broke a few weeks ago and so far the media generally seems unenthusiastic about covering the story. Most people I've mentioned it to haven't heard of it yet; that's the media's fault.
It's not like it's difficult to find FTX in the news anyway.

I tend to agree. I've never spoke of theranos or EH with friends or more specifically my wife. The other day she brings it up...
"What do you know about Elizabeth Holmes? She just had a baby and is going to jail for 15 years"
The pregnancy / child / jail is what made my wife interested. I told her that I didn't have much information on the subject other than the company said they could do x, pulled in a ton of cash, and couldn't do x. She then proceeded to watch every documentary / book / article she could find on EH and Theranos.
It was the pregnancy topic that made my wife interested. Not the amount of money or fraud, pregnancy which is something she can relate to.
I don't think the media turned into a mob until after the book, as you said.
*edit: phrasing
If you borrow $100,000, the bank owns you. If you borrow $100,000,000, you own the bank.
The bigger you are, the longer it takes the establishment to bring you down, if they ever do.
If I were the prosecutors, I would let him keep hanging himself with on the record interviews for as long as possible. Everything he says seems to make the case easier to win.
