I don't know the terms of the commercial licence in question. But GPL programs can be sold. http://www.gnu.org/licenses/gpl-faq.html#DoesTheGPLAllowMoney http://www.gnu.org/licenses/gpl-faq.html#DoesTheGPLAllowMone... Does the GPL allow me to sell copies of the program for money? (#DoesTheGPLAllowMoney) Yes, the GPL allows everyone to do this. The right to sell copies is part of the definition of free software. Except in one special situation, there is no limit on what price you can charge. (The one exception is the required written offer to provide source code that must accompany binary-only release.)
