I agree with the ETH evaluation, because of the fact that it can be manipulated by a single party essentially due to the sheer amount of influence this person has over the community. Also, it was ICO'd, which probably makes it more suitably categorised as a utility token, or security.

I think that classifications themselves don't really matter that much on paper. It's not a matter of principles, but what these classifications bring in terms of tax and regulations.

I'm no expert in this field, and I'd be interested to know how would something being classified as a commodity be different from a regulatory viewpoint compared to a currency?
