That's too bad. Gosh at 100,000 units of sales per year, the supply chain isn't interested in producing parts. That still a large niche. I guess these companies like SRAM can't afford or aren't interested in producing their own sub components.

I have a SRAM i-Motion 3 sitting on a shelf. I replaced that with a Sturmey Archer x-rf8. My 20" folder as a Shimano Nexus 8 in it. It appears I have all of the big three IGH's... or at least the ones mentioned in that article.
