The spots are locked with the factory for a lump sum cost, any negotiation to change the design distribution may affect the pricing.
If the MOQ is not met for Reflex by the deadline, the GB will be cancelled, including for the Paradox.
The design had a long IC thread, was featured on Top Clack twice as well as by other channels, and was "lively discussed" in various Discord channels. I think it has reached most of the audiences that will likely spend this amount on a custom keyboard, and not really for lack of promotion or awareness.
