I think circumscribing would be a better choice of word here:

"...without introducing a censorship architecture and circumcising constitutional freedoms."

The translation is fluent, and I shouldn't make fun of it, but that line made me laugh.

On a more salient note, it's good to see that these proposals are not proceeding without public notice. It's hard to fight the "FOR THE CHILDREN!" brigade, but fortunately the Germans are having the debate openly, paying at least lip service to constitutional process.
