If multiple network interfaces defines a router, then every cell phone is one, because every cell phone has a cellular and Wifi interface, and is a router in hotspot mode. Three interfaces if you count USB which can also be a network interface (hotspot works over USB in both Windows and Linux) and four if Bluetooth PAN is still a thing.

Speaking of phone companies, Apple will be manufacturing Mac Mini in USA.

If Apple can make a Neo laptop out of phone parts, they could make a US Airport router out of US mini PC parts.
