What you have to understand is that Facebook is effectively the defacto global identity system. Russian bots and astroturfing aside, it's still the most widely used and deployed identity verification service around that is borderless and not government controlled.

Yes, they don't have penetration in every country in the world (i.e. in China). But they effectively own identity services in the Western world. For blockchains, one of the key gaps in adoption is validating and verifying real users.

If I'm one of the blockchain startups doing identity verification such as Civic or Status, I'd be very worried right now that the 500 pound gorilla is getting into the game.
