There seems to be a semantic argument going on here. As I see it, there are three terms at play - "Open source" - "Free" - "Libre" and again, as I see it, they all have mutually exclusive definitions. ie. - the source is available to see and compile - the project may be used without financial expense - you may do with this project, and its source code, what you will (and personally I accept the restriction that you must preserve that right for others as not compromising this.) under these definitions, I would now call the UE4 engine free and open source. I would not call it libre. Do you object to any of these definitions? |

In this context, all of them (well, maybe not "Libre", for which you have an approximation of the usual definition.) The common combination "Free/Libre/Open source Software" phrase comes from three different names for approximately the same thing in Software:
(1) Free Software under the FSF's Free Software definition [0]
(2) Open Source Software under the Open Source Initiative's Open Source Definition [1]
(3) "Libre", a term sometimes used parenthetically to distinguish Free Software in the Free Software sense as discussed above from free-of-charge (gratis) software.
