This issue is relevant to non-US persons and countries because the USA is actively trying to prevent Huawei from doing business in these countries.
The US-centric views are so prominent on the HN that sometimes I wonder if ever anyone at the silicon valley intended to "Make the World a better place". How can you make the world a better place if you cannot recognise that a world beyond the USA exists? It's even in your statistic! Turkey or Sweden is not simply some data points, they are real countries, allies of the USA, with their own interests.
The Europeans are often accused of being anti-American but maybe that is not the case, maybe it's just that Europeans every once in a while need to protect their own interests and that is perceived as treason.
There is no reason to be so smug in explaining obvious things and assuming complete ignorance on my part.
