Private blockchain (one that is centrally controlled, usually internal to a company) or privacy blockchain (the flow of funds is obfuscated)? Private blockchains lack decentralized consensus, so the have more in common with a typical database than they do w public blockchains. Given that they are normally used inside a single company or between a few companies who already trust each other, i don’t see any ethical problems.
