Terrorists who fight governments we dislike are called "freedom fighters". Terrorists who fight governments we like are called "terrorists". Other governments and groups apply the same distinction, and since different folks like different things, almost anyone out there who uses violence will be called a terrorist by someone and a freedom fighter by someone else.

Whether or not anyone in the picture, those who fight governments or the governments they fight, has any concern for anyone's "freedom" in the literal sense is generally irrelevant to the nomenclature.
