@rml @vagrantc @ekaitz_zarraga @loke And nobody hsa really argued anything else. Just like the GNU GPL imposes some extra stuff on being able to know how to build the program.
But that too .. is not related to software freedom, but making sure that the gap between one party and the other is made non-existent, e.g., see DRM in GPLv3 to make sure that those who can make a signature, also much allow others to _chive_ the same thing.
