公眾授權條款的推動是貫徹自由文化運動的重要方法與策略，然而，由於不同種類授權條款彼此間存在著不相容的問題，自由文化運動正面臨著資訊、社群、創作人及個別著作被割裂的危機。本文以自由文化運動中最重要的兩種授權條款——創用CC授權條款及GFDL——為核心，析述授權不相容對於協力創作及重新混用創作方式所帶來之負面影響，並站在授權人之立場，觀察兩種授權條款之差異性。此外，本文亦介紹兩種授權條款近年來在促進彼此相容所作之努力及其侷限，同時就自由文化運動及授權條款相容性未來的長期發展，提出相關建議。

Promoting public licenses has been a crucial approach and strategy to free culture movement supporters. These licenses not only enlarge the scope of intellectual commons, but also reinforce the value and social norms underlying the movement. Nonetheless, as more and more public licensees emerge in the free culture communities, the freedom granted by these licenses is not elevated accordingly. On the contrary, intellectual commons, communities, and creators are increasingly fragmented because of the incompatibility between different public licenses. Using two of the most important licenses—Creative Commons licenses and GNU Free Documentation License—in free culture movement as examples, this Article illustrates how license incompatibility has become an obstacle for peer production and remixing creativity. This Article also analyzes the subtle differences between the two aforementioned licenses. Such analysis may help explain dissimilar preferences of a wide range of licensors and why various licenses simultaneously exist in the free culture communities. Furthermore, this Article provides a strategic guide for communities to solve the incompatibility problem.
