As I understand it Larimer graphene blockchains are not exactly decentralized. You can easily buy a stake in it to vote or be a witness if you have enough money. The reason for the EOS tokes being released for a year was to try and stop whales eating up all the network to make it centralized like has happened with Steem. I don't think that this will work though and if the tech works as they claim, large corporate interests will take over the whole system very easily and screw everyone.
