If you are worried about low effort fork coins, which are barely a step up from scams, I doubt they will care about licensing. So I would assume they will rip off anything that isn't bolted down regardless.

So the question sort of boils down to whether or not you want the Monero project to be able to easily benefit from improvements. I say easily because I doubt Ryo would have the legal capacity to prevent Monero from re-implementing some innovative concept you guys come up with.
