There is a far simpler way to look at this, and that is to say that this is why we have peer review in science. If a scientist won't release data or methods, there is a 99% chance they are bullshitting their claims. Theranos's product happened to be adjacent to my research space, so I was already highly skeptical when I heard the initial product claims. When I heard they weren't releasing data however, I strongly suspected they were bullshit. Many years later, sure enough..
