The good thing is that google in Germany now shows how many reviews were removed due to deflamation. That should be enough for people to make their judgement when checking how many stars a place has

That's just the tip of the iceberg though. Google is the only party who meaningfully communicates this, and it took them years and years to introduce any meaningful transparency.

It's not like this exclusively affects restaurant reviews, every corner of German society is subject to this same evil censorship mechanism.
