You call the act under "pressure and threatened sanction" voluntary?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.
Who cares? You certainly care. Is there any difference? Certainly a huge difference. Because the answers to those questions touch the very bottom of what you were trying to say "Those countries and even Chinese companies are hoping on the bandwagon of the US against China/Huawei." To this I disagree.
Regarding Huawei being abandoned by Chinese consumers, don't make things up (a lie) since you certainly does not live in China and has absolutely no idea of what people there is doing. Besides, Samsung and Apple was abandoned by Chinese consumers in a lightning speed, if you really wish for abandonment of Huawei in China, you may not be able to live that long to see it happen.
The US had "so great power" to compel everyone? It only have the power to compel people whose spine has already been broken by the US, or who have already sold their soles for a cent. Talking about US compelling everyone? Just see who was bothered by the "reimposing sanction on Iran" drama in the UN, NONE.
Seek better relation? You mean surrender? China beat the US in 1950s, so will we do so in 2020s when we are much more stronger than we were in 1950s and the US is much weaker today than they were in 1950s. A better relation for China with US can only be based on victory over US, period. That is the lesson we learnt from Korean and Vietnam.
