Sometimes this type of long form journalism is nice because it lets you marinate in a different world. Here I can't help but feel like I just want them to get to the point because I don't really want to marinate in the Flat Earth world.
If a super intelligent AI came to me and said, "I'm going to take over the world and destroy humanity, but first I wanted to see if there was anything you needed." One of the things that I would ask it to do in order to buy time would be to annotate all the background details of every movie. For example, in Jurassic Park when Hammond is trying to get Dr. Grant to come to the park, the trailer they are in has a bunch of newspapers on the walls. What do those say? Who are all the extras that are hanging out at the dig site? Like who are the actors and can we give their characters any backstories that are consistent with the world of Jurassic Park.
I can't help but want the same thing from a story about a Flat Earth conference. How many other people went there just to see what was up. Who is there as a joke. Occasionally people send fake articles to journals to see if they can get them published. Does the same thing happen to Flat Earth conferences? People try to see how much of an outlandish presentation they can get away with? And finally, how many people go there, have a good time, pretend to buy into the whole Flat Earth business, but then when they get back and are cornered indicate that they only went because their friend went / to see what it was like / because they make fun of them later / etc.
Finally, this whole business feels very similar to me as the whole Evolution in education stuff. Sure people believe in the wrong thing, but at the end of the day very few people actually understand how the right thing works and even if they get that far they don't see what any of the implications are. Yeah, I would prefer people believe things that are true, but they don't understand it either way and they refuse to think about the implications.
I greatly appreciate the world building in things like Lord of the Rings or Avatar the last airbender. Everything works together in great detail to create a holistic world where actions have consequences that echo through the centuries. It feels like most people are just as happy to watch Michael Bay's Transformers. Maybe they like Avatar as well, but they don't understand why the shyamalan movie "adaptation" is bad. So I have a hard time caring that they agree with me that the cartoon was good as well.
