Libre is a prerequisite, gratis isn't. This is an important distinction to make. While it is true that this software seems to be neither, it is important to note when we try to convince them to release it free, we mean libre and not necessarily gratis. (Although the two often go hand in hand.)

When people hear us complaining about it, they often think we want to avoid paying money for it. This is false, and a bad impression to give. That is the purpose behind making this distinction.
