I had the same question for the author of the article, but it's understandable that people are going to be cagey answering this question because they may not want to give away spoilers.
If anything that's the part that convinces me it's more than just a documentary, the fact that people apparently don't want to spoil what happens.
Well, yes. We know the plot, but we don't know in what light the movie casts here, and how they do it.
Then what was the point of bringing Amanda Seyfried into the "documentary" as a major character?
What does Amanda Seyfried actually have to do with the story of Elizabeth Holmes and Theranos?
You Can See Everything doesn't have Amanda Seyfried in it as far as I'm aware.
