But that has nothing to do with DPoS...
You're talking about how blockchains can fork, that's not DPoS. Delegating Proof of Stake is only the act of voting on someone ON-CHAIN to decide consensus for you. That failed hard. If you're trying to say that Hive as a fork was a success, then you're talking about an off-chain solution being a success.
All I have seen from this mess is that DPoS is a complete failure and any blockchain using it is not sufficiently decentralized to be secure. Not to mention, with the resent lawsuit against EOS alleging that EOS is not sufficiently decentralized enough, it appears the government might soon rule that DPoS is not decentralized.
