> Huawei even let the UK secret service inspect Huawei networking gear, e.g. [1, 2, 3]. They only found badly written software, which is hardly unusual. Which, by the way, is the perfect cover for a backdoor, because it's deniable. Furthermore, even if you're looking for a back door, there's no guarantee you were actually looking in the right place (for an example, see https://en.wikipedia.org/wiki/The_Thing_(listening_device) https://en.wikipedia.org/wiki/The_Thing_(listening_device)) > A much more likely explanation for the US sanction on Huawei is simply anti-competitive measures. No, it's 100% geopolitical maneuvering. IIRC, US companies don't even sell competing equipment in many of the relevant areas. You don't need "evidence" of a backdoor in order to distrust something.
