How do you kill a company? The answer, in the context of Chinese electronics giant Huawei, appears to be depravation, removing ready access to the elements that distinguish smartphones from very expensive chunks of anodized aluminum and glass. The latest blow: Chip designer ARM has reportedly severed ties with the company. Huawei could arguably survive without Google. Without ARM? Not so much.

It’s important to clarify that nothing at this point is certain, or permanent. The BBC first reported ARM’s move Wednesday morning, citing an internal memo that noted ARM’s use of "US origin technology,” which makes it subject to a sweeping ban put in place by the Trump administration. As it did with Google, though, the US Commerce Department could grant a waiver that allows ARM to continue servicing Huawei. And broader tensions between China and the US could otherwise resolve, potentially taking some of the pressure off Huawei.
