It's a good video that shows how that weird conspiracy doom bubble feeds itself. Guys like Brand, Rogen, Jones, and Carlson are all in that mode of working together and promoting each other to expand their audience. They do it under the idea that "Well, we are just asking questions and having a conversation!" but where they want to point people with those questions and with that conversation is the same place. 

I wonder how much they really are joined together, because I think they all know that at any point any one of them could completely lose their audience. At which point the others adjust to stay riding the wave and generally a new person or persons will be brought in to replace the guy that fell. 

I do think the thing about that podcast universe is they don't really have to fact check at all. They can converse and question but there is a path that they stay on when they do and at the end of the path, the audience is meant to leave feeling suspicious, doomed, and mostly determined not to trust anybody except for the people they heard "asking questions."
