I'm confused by this article. I agree with the author that the flat earth coordinate model as advocated by him can converge with the spherical model if we allow it to account for changes as we move away from the poles. But I think he misses the point why people hate or discount the flat earthers. I don't think they are advocating for a practical model that works in approximation. Their illustrations literally seem to portray the earth as a flat pan. For our 3D perception that is not true. It's nothing to do with how we measure distances on the ground. That's the image or belief everyone is fighting against, not against a particular coordinate system. The phrase flat earth is misrepresented in his article when compared to popular parlance (https://video-images.vice.com/articles/596717d19d542017b4db7c15/lede/1499928541955-flatearth-1.jpeg https://video-images.vice.com/articles/596717d19d542017b4db7...). So we aren't even talking about the same thing.
