Strategic reasons for choosing different licensing models exist. The Free Software Foundation itself reccommends using different licensing models for software libraries depending on the situation: • No copyleft for libraries that implement proprietary standards competing with open standards, to further adoption of the implemented standard among proprietary software developers. • Weak copyleft for libraries that implement the same features as existing proprietary software, to further adoption of the library among proprietary software developers. • Strong copyleft for libraries that “do not face entrenched noncopylefted or nonfree competition”. https://www.gnu.org/licenses/license-recommendations.en.html https://www.gnu.org/licenses/license-recommendations.en.html
