It means just that it makes no sense to answer that question based on human morals ... doesn't mean the answer is set in stone.
It specifically doesn't mean that one non-human entity should be treated the same as all other non-human entities.
For instance an argument could be made that it can be moral to cheat the State, but not Society. It's not an argument I want to discuss now, but the point is, you can use ethics and come to different conclusions about entities that are not human beings ...
Is society human being? Is nation a human being?
If not then is it moral to deceive and cheat them too?
