I would argue that you have a moral obligation to do something about this while bearing in mind your own needs and obligations (e.g., as a breadwinner for your family).
Others have been in your situation before. Try seeking advice from Tyler Schultz, one of the first Theranos whistleblowers: https://www.linkedin.com/in/tyler-shultz-450923126
There may be others, I’d love to see comments giving other suggestions.
You could also get in touch with the Wall Street Journal— tip line is here https://www.wsj.com/tips
You could send a message directly to reporter John Carreyrou, the WSJ reporter who worked on the first big Theranos story.
Going directly to the press has some serious risks — legal risks especially. That’s why you might first begin by merely seeking advice and input from people who have worked on this before.
Many people will tell you that the legal risks mean you shouldn’t do something. I understand that position. At the same time, I believe we human beings have an obligation to each other to deal fairly and honestly, and to help bend the world in that direction. It’s not an easy position for you to be in. Good luck.
