Ah, I see. Honestly I understand the concern about USB-C, but first of all, all the USB-C exploits require physical access, so that eliminates some worry. And USB-C without DMA is going to be similar to USB-2 in terms of security. So using someone else’s charger is going to be about the same amount of danger (if not less) as plugging in a USB2 thumbdrive. Close to zero on linux.
Any way we can ping Purism Staff for more info?
Also, I found this… Librem13 USB-C Charge Hack Thoughts?
Apparently a couple people already opened up their librems to put in a USB-C => DC converter.
