Free software licenses do not expire, which means that once Free Software is adopted, institutions remain independent from the vendor. Moreover, Free Software licenses grant users the rights not only to use the software as they wish, to copy it and distribute it, but also to modify it in order to meet their own needs. Therefore, if institutions eventually wish to implement a particular function in a piece of software, they can engage the services of any developer to accomplish the task, independently from the original vendor.
