The ultra-advanced, superior technology of the digital currency Bitcoin and it's Blockchain public ledger system are in danger of being co-opted.

Taking a quote from your post, a true bitcoiner will be able to differentiate between a real crypto and something which is not, so I don't think in any way these cryptos (whatever they decide to name it) controlled by a central banks will ever become a threat. If centralization means anything, it has to be the first priority on why we chose to move away from fiat going to cryptocurrencies.
