I have watched the first video and read all the transcripts for his Bill Gates series, and think I have got a good idea of his style:
Corbett seems like he has taken the slickness of the Kony 2012 video and made ones about Bill Gates, but his message isn't the facts or clips he presents, it is always implied. The reporting narrative builds a story consisting of ideas in quotes, or statements written like a question, then you join him as he seeks through his own thoughts what those answers might be, what the truth *really* is.
The videos are like a tangential thought process in narrative form, but each tangent is not a new fact to consider: The tangents are suggestions of explaining Bill's actions or words, tangents are on second guessing motives, he reinforces those ideas with stories and opinions related to the gruesome topics of 'Bill's master plan'. He builds on the previous guessing by using crafty language to omit reflection, and incomplete unchallenged reasoning. The process results in painting those explanations into a smear with a huge question mark afterwards, as if he was just asking questions and not making allegations. There is no proof that Bill is planning a mass murder or genocide in line with an evil world view, no evidence he plans to microchip the public without consent and lord over them like they were slaves, these ideas are implied by the detailed and captivating picture he paints.
I'm not doubting Corbett is an intelligent man, he is smart, well spoken and written, he knows how to tell a story for sure. He is talented in video editing and knows what clips to play and when, what quotes to use and how, all of this tells an interesting and chilling story. But either he has become obsessed with filling in the gaps with the worst things he can think of, or he just loves the power he has the ability to wield over the viewer, because what he is doing is not right. This isn't journalism; it is an attack of allegations based on weak reasoning that purposely avoids reflection and alternative explanations, avoiding anything that could damage and challenge the narrative he creates.
