"Tyler Shultz, a Theranos employee from 2013 to 2014 and the grandson of then-Theranos director, former U.S. Secretary of State George P. Shultz, was a key source for the WSJ story. Shultz had attempted to bring his concerns to company management, and when that had failed, he had spoken to Carreyrou and also, under an alias, reported the company to the New York State Department of Health." - Wikipedia
Still, seems hard to believe as you said that it took as long as it did. The company was founded in 2003!
Here's a recent article on Shultz and his reaction to the verdict:

"It was clear that there was an open secret within Theranos that this technology simply didn't exist," Shultz said.
It does seem pretty striking that there weren't even MORE whistleblowing and earlier, but I guess many just are blissfully ignorant and don't want to "rock the boat."
I haven't read the book either, so am not as knowledgable about the happenings as other posters...
