Putting a chip on an M.2 card doesn’t cost that much. Hopefully other manufacturers will appear.

Maybe I’m not 100% right, but this is exactly what I understood: Purism as Finished Product Manufacturer! As of Feb 9, 2019 this goes for M.2 modem card as well:

Another critical component is the cellular baseband modem which might be concerning and for that we will use a modem Made in Germany, put on a modem PCB in the USA and which will be implemented into the devices in the USA during final assembly.
