How can we protect ourselves from this type of interception? It seems impossible. Why would any non-american customers buy US made devices? Any protections that are added can/will be bypassed if the US gov gets physical access (or even remote).
Software is not a concern as I blew away the preinstalled and put a relatively trusted OS on. But hardware - I haven't had time to look into it but I'm still wanting some sort of guide on what to look for after unscrewing the case.
