Nope. Not the crypto enthusiasts, but that might not matter. People are already used to some kind of points rewards or tokens through the use of credit cards and the like that are then redeemable for purchasing items. So, it's not a big a stretch, if presented correctly, for Facebook to tell it users that their crypto is available for use on Facebook, or however they intend to do it. I don't think they'll need the enthusiasts, not with a billion or more users to draw from. Even if they end up with 10 million people regularly transacting, that could be a problem.
