FCC maintains a list of equipment and services (Covered List) that have been determined to “pose an unacceptable risk to the national security.." FCC Updates Covered List to Include Foreign-Made Consumer Routers..

I disagree with the FCC. Banning "China routers" will not meaningfully increase security. Actual security has no correlation with country of manufacture.

"national security" and "security" mean very, very different things in this context though.
