When I heard that ARM was to stop doing business with Huawei, I was a little bit puzzled as to how that worked: ARM is a British company owned by a Japanese conglomerate; how was the US able to extend its influence beyond its citizens and borders? A BBC report indicated that ARM had concerns over its US origin…
