At what point does a fork stop being a fork?? It's more of a "stick with a wiggle" than a fork in this case.
I think this is a super interesting design FWIW. I'm very curious if it feels "noodly" when riding due to decreased frame stiffness, but that might be an acceptable compromise for people who want a very small fold without all of the downsides to a brompton (price, non-standard components, etc).
