I came across an NPR Article this morning discussing malware believed to have been installed by China on many small office / home routers across the United States.

National Cyber Director Harry Coker Jr. alluded to the fact that the US does the exact same thing by advising The House Select Committee on the Chinese Communist Party to "continu[e] operating with confidence, not yielding the initiative, not merely staying on the defensive, but being as strong as the United States has always been"

The vulnerability that was exploited was "outdated Cisco or NetGear devices that were no longer subject to software updates." These vulnerabilities were present because proprietary equipment and software was no-longer being maintained. This is far less likely to have occurred with routers using FLOSS, like OpenWRT. Such routers regularly receive updates for many years after the original equipment manufacturer has stopped supporting them.

Only with FLOSS hardware, software, and shared standards can nation states have digital sovereignty, compatibility, and security. If all sides are using the same FLOSS standards, then they can host their own services without dependence on a foreign tech sector, they can maintain international compatibility, and any vulnerabilities affect all parties equally. Therefore, it is in the best interest of each party to contribute fixes which ensure their own infrastructure is secure, and simultaneously provide security & functionality to each other party.
