I agree it's an issue but maybe we are going at it from the wrong angle. Why just be scared of the Chinese? We should protect ourselves from both domestic & foreign adversaries.

Any electronic device with vision, sound, or radio communications capability should be required to be source-available or at least independently audited. Proprietary code must run in sandboxed black-boxes that can't directly communicate/interact with the outside world.

Sounds like an impossible ask? Well, banning Chinese robots/routers is also an impossible ask.
