"teaming up against" is wholly wrong interpretation of their true intention. Let me put forward another example, when Trump reimposed sanctions on Iran, lots of European companies were forced to stop working through their agreement with Iran, does that mean Europeans were "teaming up against" Iran and Iran Nuclear deal? The EU's open objection of any EU company complying the American sanctions tell the opposite. Same here and today.
"teaming up against" is the act by voluntarily action, it is intentional. Prevented to continue working with Huawei is totally different matter.
It is voluntary though. The US has no jurisdiction over Europe or Korea or China. They could say screw the US, we are developing our own independent equipment and supply chains. But will they do it? No they won't. And even if it were involuntary, who cares? It makes no difference. At the end of the day, they choose to comply with the US, they will comply with the US. That is all that matters.
And not only chipmakers, but China's own consumers will abandon Huawei. Don't think the home market is safe. You can talk about patriotism all you want, but not many people want to go around with an inferior phone just to be politically correct.
And not only China's chipmakers and consumers, but Huawei's own employees will abandon Huawei. They already are, as many of their talented designers have jumped to other companies. Oppo. Vivo. Xiaomi. Samsung. Apple. There are plenty of alternatives. At the end of the day, no opportunities, no salary, no workers.
In short, Huawei will have no friends. The US government's power is so great that it can control and compel everyone. That is why China should seek better relations with the US instead of fighting.
