What was deceitful about it?
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.
I'm guessing it's because she's still trying to control the narrative even though she's literally just waiting until her prison date.

They show Holmes reluctantly watching the movie "The Dropout" which is a dramatized version of "the rise and fall of Elizabeth Holmes" starring Amanda Seyfried as Holmes.
Later in "You Can See Everything" Amanda Seyfried literally becomes an important character in the documentary including voicing her opinions and impressions, arguing with and challenging Holmes' husband Billy (they have just met for the first time) and talking at length with Fielder about his opinions and impressions.
This inclusion of Seyfried in this manner ruined for me any chance of this film feeling like a "documentary." This is the point for me where the film went "off-the-rails" and begins to feel like a very confusing experiment in audience manipulation.
It suddenly feels contrived because of this.
