Following the debate of Chris Pearson and Matt Mullenweg over GPL theme. We would like to take the opportunity to clarify our theme licensing to avoid any confusion.
Drupal is an open source software covered under GPL (ver. 2), all derivative works based on Drupal are GPL as well. That means portion of our codes that are derivative of Drupal such as theme settings and template files (basically everything ending with .php or .inc) are covered by GPL and may be freely distributed.
The “look and feel” of forDrupal themes which includes files not dependent on Drupal, typically images, javascript and CSS are not subject to the GPL and are the intellectual property of forDrupal and licensed to you upon purchase via our website.
