There are a lot of possible nuanced conversations but I think that the rejection of FB-coin on principle is the simplest argument and doesn't require much nuance to achieve. That principle simply being the principle of decentralization which is core to the concept and purpose of block chains. No single or cluster of large companies or governments can create and control a block chain without violating that principle and thus a rejection on principle is justifiable.
