We wanted to make a user-made expansion, for free, for you. If it was licensed, we'd have to charge for it, and no one wants that at all. Quality is assured - have a look at the other projects the members of Artifex have released, and it shall be released at ZA, where it will be thoroughly tested before it is available to make sure it works as it should do. Your thanks and enjoyment of what we will release is good enough for us, we simply don't need Blue Fang to recognise our efforts. We are making this expasion for you, the end users of ZT2, not them.
