+				\item \textbf{Restricións de uso:} Restricións excesivas, limitando a capacidade de integración con software propietario.
+				\item \textbf{Compatibilidade:} Pode ser incompatible con outras licenzas, dificultando a colaboración entre proxectos.
+				\item \textbf{Modelo de negocio:} As empresas deben adaptarse a un modelo de negocio que non sempre é viable.
