Decentralization of a Facebook cryptocurrency could mean that the digital advertising duopoly of Facebook and Google would die. Just because it could die doesn’t mean that Facebook has anything to fear. I believe Facebook can structure its cryptocurrency so that the interests of all involved are met and exceeded. This includes the interests of Facebook shareholders, users, employees, and ultimately all of the participants in the Facebook Coin transaction economy.
What the hell can a centralized monopoly which uses its power to supress debate and increase the strength of its own narrative have anything to do with decentralization and empowerement of the individual?
That's certainly simply not true.
