I think that most of the world is greatly overestimating how much power Facebook and Zuckerburg are actually going to have regarding project Libra.
Everyone just assumes that because Facebook and Zuckerburg are creating the thing that they will control it. That's not going to happen. There's a reason it's being set up like it is. All 100 corporations are going to have a little control. This will make it way way harder for banks/governments/regulators to attack it.
It actually looks like it's going to be decentralized from a corporate point of view... I think it's going to surprise everyone and be quite the spectacle.
