IMO moonlander, ergodox, etc .. all just shitty Advantages. The only thing that comes close in the DIY/Enthusiast community is the Dactyl. Nothing beats the contour.
I'd say that it is more their response to the Dactyl[1] and the Dactyl Manuform[2] which is similar to Kinesis but split.
Those started as open source DIY keyboards, and originally you had to 3D-print, hand-wire, solder and program yourself, but ready-made ones are available now.
