I kinda doubt cryptocurrency/blockchain tech will be anything but an implementation detail in this project. Assuming this catches on, the idea that Facebook and it's other partners would let this get out of their control seems very unlikely -- and if it did get out of their control, I think they'd simply abandon, disavow, and/or fork it. The appeal of this to users is going to be integration with the social networks these companies run, so they are holding effective veto power since they can change its relevance to low at any time. Meanwhile, the partners will be tracking every transaction and monetizing that information. Apparently, you can use a pseudonym when using this currency, but I'm sure they will connect any pseudonyms you use to your profile the second you first use them. Wonderful.
