Well, no. There is plenty of room to debate definitional questions around open source. For example, is open source even the right goal, or should we be aiming for something different, like free software? Is the GPLv3 a step forward from GPLv2, or not a great idea? Wherever you come down on those questions, I think virtually everyone involved with open source or free software would agree that part of the appeal of such software is that you don't have to pay license fees to use it.
