My 2c: I doubt they'll win but it's likely a ploy to show the rest of the world that the US govt is full of shit when they accuse them of spying for the CCP. If the US can't prove their claims in court it'll be like a clean bill of health for Huawei's telco gear. Even if the US never uses Huawei there are loads of countries (like mine) being arm-twisted to refuse Huawei gear in our future telco infrastructure, even though we've already been using it for years.
Additional 3 cents: I think each country should have their own internet with full autonomy & run our own versions of Amazon, Google, FB etc. Otherwise we're going to be pumping megabucks into the US economy just to trade this century. Why are local businesses advertising to local people paying an American firm for that privelage? We all need Great Firewalls. I think China's great firewall is their best asset (after their people), even though they probably set it up for sketchy reasons. It's not just about advertising $$ either, in the information age, we're being harvested for our behaviours online & that big data is highly valuable. We're giving it all away for free to companies in California.
