Unless this whole project is one big conspiracy, I don't see how this is true.
Libra will be governed by at least a couple of dozen big corporations, some of which are in direct conflict with FB's agenda. FB will have to convince 67% of the nodes to make any non standard action and keep it a secret. That's a huge business risk.
And from my reading of the white paper I don't see how you can actually block an address from submitting or receiving transactions. Am I missing something?
A lot of people in this thread don't distinct between Libra the currency and Calibra the Facebook wallet.
A wallet controlled by Facebook is indeed worrying, and I hope that there will be enough worthy competing alternatives.
The Libra network on the other hand looks very solid.
