Since this is a decentralized application running as an Ethereum smart contract with IPFS[1] interface, the move will not actually deter any state actors from using this, but will criminalize and stigmatize regular users who want to anonymize their Ethereum transactions.
The end result may be as the government wants: force users back to fiat so they can maintain maximum control of funds, and anyone left in the mixer is default a criminal.
