European Data Sovereignty
As far as I'm concerned, it is just not compatible with Google.
Huawei has now been baselessly accused of handing over data to Beijing for the past four years. Google is a US company and everyone knows that an National Security letter will get any data on Google servers anywhere in the world.
So if you want to enforce European Data Sovereignty, the sine qua non condition is to have nothing to do with a US company.
It's simple.
