It is absolutely relevant. It is completely within the realm of feasibility that a foreign nation state would pressure a manufacturer in their jurisdiction to include a backdoor, or simply insert it themselves. Routers are in every home and office in the country, and can be leveraged for immense attacks. It’s a hugely attractive target, and it’s a reasonable security policy to try to limit our exposure to this threat. And it would absolutely make sense for adversaries to avoid buying U.S. made routers for exactly the same reason. Unfortunately this administration is generating more adversaries by the day.

My point is that the US did alter homemade products for export, and that the only people litigated against were the whistleblower and/or companies providing service to him.

> If US manufacturers (or manufacturers in allied countries) do this, legal avenues exist to hold those manufacturers accountable.

With that context added, my point is that the US judicial system would never litigate against e.g. Cisco if they were involved. The issue is not the relation between the state and Cisco, it's the relation between the US justice system and the US national security apparatus that prevents any such litigation to happen.
