It's both, honestly.

(1) I can't incorporate Hibiki into anything (A)GPL licensed, which many of my projects are.

(2) Ideologically I can't get behind something non-free, even though I completely understand why you wrote the license the way that you did. Realistically all it's going to do is hinder adoption (see parent comment of mine).

(3) You can say I'm not going to get into trouble, but your license says otherwise, and I really can't use something unless I'm 100% sure I'll be in the okay, ya'know?
