This is not legal advice. No lawyer-client relationship is established. etc.

This is plain wrong in all copyright laws that I am aware of, including 
Germany. The basic principle is that creation of a derivative work (or 
whatever the term is in other laws outside the U.S.) is an exclusive right 
of the copyright owner. That means someone needs either permission from the 
copyright owner (e.g., license) or rely on some other defense (e.g., fair 
use, de minimis, etc.).
