No, I'm asking if it was designed by Flat Earthers
This was just answered.
It was answered with an apparent misunderstanding of the scope of the question.
No one here or in the links you posted ever made that claim.
Certainly Tom has.
Read Earth Not a Globe, please. The same model was used 150 years ago.
All of those originate from the Flat Earth maps in the 1800's.
even that the geometrical transformation formulae which project the globe into this configuration were actually concocted after the fact.
After what fact? Purposely being vague to try and squeeze "gotcha!" answers out of someone is quite silly.
I was trying to be succinct, not vague. It's a common idiom, at least in my experience, and I didn't think it would cause any confusion. What I mean is that Tom claimed that the map in the FAQ was not produced by -- nor based on something produced by -- the formula which produces a map that looks exactly like it. Rather, they invented it from scratch on their own, and then
after it already existed, Round Earthers cleverly devised a formula to transform the globe into that configuration.
