alt Hacker NewsQualcomm is a US company right? I've worked on a few WiFi router devices and their chips are pretty popular in that segment. But WiFi is not a priority for Qualcomm (in fact they actively sabotage it for their more profitable 5G segment), and software is even less of a priority. So you had "parsing 802.11 TLVs in the kernel with obvious stack overflows" quality code drops.
(Which is why it's a bit ironic I saw the Google Fiber guy post on X about how they always had TPM^TM "security" in their routers; thats cool, but the drivers you used still made them "general purpose computing over the air" devices)
Doesn't matter where they're headquartered if they use foreign-made components. I don't think there's a robust enough supply chain of domestic materials available (nor cheap enough labor) to feasibly stop using foreign-made components.
