There is an inferred "Speaking as a German", so the author is a letting me know they're German.
But also as you pointed out it makes no sense for them to assume I'm German, but it does make sense if they are German. So I'd just assume the version that makes sense.

Yes, there is the "speaking" part inferred, but the grammar still does not
work like that. As a supposedly educated English native speaker, you should
know better.
If I said: "As an idiot, you're wrong", I could not possibly claim that
I called me an idiot. Why suddenly the subject would change in the very
same sentence structure?
I see the difference and I wish I could have the privacy of no ID cards back.
