"No more updates" ain't bricking.
I know that's not what the word "bricked" means.
Ultimately, this may erode trust in US-based tech companies in general, which for the long game may play into Huawei's advantage if they manage to come up with a viable competing platform.
If that is true, that will be the basis of the biggest class action lawsuit in history, against Microsoft from every single company in Europe now being left vulnerable to attacks.
Microsoft knows that, which is why they will do everything in their power to ensure this is never happening.
In general, Microsoft's mechanism and architecture for OS updates are clearly superior to whatever Android has, since they can be applied blindly and generically across devices and units, with stupid proxies and mirrors in between.
More important than architecture though: Microsoft has fought the US government in the past when they have tried to enforce things Microsoft has disagreed with (like US governemnt blanket access to MS-owned EU datacenters).
I'm pretty sure they'll fight this one too. Their quite significant EU business depends on it.
Edit: Quite possibly Windows will not receive updates on Huawei laptops anymore.
