Google, Arm etc. don't want to stop doing business with Huawei (since doing so no doubt costs them a lot of money), they're being banned from doing business with Huawei by the US government.
Also google, are they so bowed down to the government, that they just accept this, or do they know more reasons to declare Huawei a enemy?
I worked for a non-Google tech company and there is literally code which prevents users in any sanctioned countries from being able to use the services.
Unless Sundar Pichai would like to go to jail, there's very little that they can do about this.
But I do not see that hapoening, so something (or quite a lot) is going on behind the scene.
Changing the law is a different process.
I rather talk standing up for free market. In a free market system the government can't just order companys to stop doing buisness with someone unless very good reasons are provided. I don't see that with Huawei. And china is Authorian? Yeah, so is half the world. But it would be news to me, that only "democracies" are acceptable trade partners.
What choice do they have ? Comply with law or be heavily fined, shut down, executives jailed for compromising nation security.
All based on a presidential order, without providing evidence.
Congratulations to US legal system then and feeling superior to authorian china.
Maybe.
Trump is doing all this under the authority of national security. That is not a blank check, though, and there is an oversight mechanism that can be employed to determine if the authority is being used appropriately or not.
Unfortunately, that oversight mechanism lies with Congress, and given that the majority party currently in the Senate is taking the stance of "anything Trump does is right", we can't reasonably expect that the mechanism will actually be used in the next couple of years, at least.
Your explanation doesn't answer the question why Huawei got picked. Huawei products got banned in the US way before the trade war, Huawei's exports to US is pretty small I'd say. It thus has really nothing to do with the existing tariff situation whatsoever.
On the other hand, there are many big Chinese companies exporting to the US in huge sheer volume, Lenovo is probably the best example here, interestingly, Lenovo never got treated in the same way. Why there is such huge difference?
The answer is plain and simple - Huawei managed to lead the 5G development and growing faster than anyone else. US refuses to accept that. Lenovo's business model is what US wants all Chinese companies to follow - focusing on low end craps, make money by working hard not working smart. Same goes to those crappy Chinese companies like Xiaomim OPPO, OnePlus.
Or you know, they were stealing trade secrets.

On the other hand, the US is super competitive. They must do as much business with China as possible in order to discourage any new company from spawning over there, because it would create competition.
In other words, Trump is doing exactly the opposite of what is good for the US.
