I think the best positioned to take over the hardware manufacture - if Keyboardio stopped - is the Chinese factories that already make the unit and will have the tooling an experience to do so.
I sugest in other threads, the Kaleidoscope and Chrysalis softwares are the crown jewels of Keyboardio. As users we should be better at advocating other manufacturers and hobbyists to use this software in their keyboards so that - in your words - becomes a commodity firmware to rival QMK. As this old Apple poster suggests, Software Sells Systems. As the main vendor of Kaleidoscope, Keyboardio (and the prospects of their hardware without the parent firm as per your original post) will benefit most from more efforts to promote this firrmware.
