You know that the word "constitution" is not reserved for the US constitution, yes?

You certainly seem to be trying to apply the standards of the US constitution to german law. I think you should be more specific if you wish to be clearly understood.

How do I seem like that when I am talking about "the constitution" in the context of German law? Maybe I should also mention that I am talking about the German NetzDG, not the US NetzDG?

Because most people write on HN in English and most HN users are American. I'm not, as it happens; but I don't know what constitutional freedoms you take for granted in Germany, as I'm not so familiar with your country's constitution, and it wasn't entirely obvious at first that you're German.

The German Constitution is pretty long so it'd be really helpful if you could perhaps cite specific articles to provide some context for your assertions.
