I think that Google has some partnership with Deutsche Telekom where they provide the software and Deutsche Telekom Runs it because Google doesn't have the encryption keys. In that case Google even if they want they cannot provide the data. Anyway that is still not digital sovereignity as Google might decide to stop providing updates or add a backdoor...

I'm personally very aware of that, and I wish Europeans dropped our collective tech-inferiority complex, but I'm currently a junior at a large corpo and that's not even my business branch; I can't steer it.
