US copyright law protects expression, not ideas.  Title 17 explicitly
excludes methods and concepts.  You are entirely free to use what you learn
from studying Free software.  This is in marked contrast to most EULAs,
which include such things as prohibitions on reverse engineering.

We need the freedom.

BTW just because you have distributed work of your authorship mixed with
someone else's GPL work under the GPL does not mean that you cannot also
distribute the portion that is entirely yours under any terms you please.
