Licensing Requirements for Modules / FAQ #7
What is the basis for the claim of http://drupal.org/licensing/faq#q7 ?
Disclaimer: I am not a lawyer.
Primary fact: Whether or not something is a 'derivative work' is defined by copyright law, not by the license.
From my reading, it seems the question is far from settled in the United States in regards to software. It seems to me that the legal validity of the claim "Drupal modules and themes are a derivative work of Drupal" is suspect.
See, for a example, http://www.rosenlaw.com/lj19.htm for a lawyer's opinion which counters the claims of the Licensing FAQ.
