This is an admirable mea culpa by the author. Sure, he is certainly casting blame on Theranos. However, he also issues an unqualified apology at the end of the article, stating "So I blew it. And I should have included all these colloquies in the original story. I regret the error." Many others in his position would have concluded with a pseudo-apology such as, "I'm sorry that I let them deceive me."
