I think he's willing to question the Heavens if he needs to and knows what needs to be kept secret, which I think is as good as we can ask for. [Shun doesn't know Ebisu well, but as long as they don't start talking actively overthrowing the Heavens as opposed to seeking peace in a way that doesn't trample everyone else in its wake, he imagines he'll be on their side.]

I know some of the other Gods of Fortune haven't been that satisfied with things like Ebisu's situation in the past either, but they're a lot harder to get hold of.
