Those accounts were not forked out. Stick to the facts please and apply logic. Anyone who did not receive the airdrop still has full control of their account on Hive and they're free to use it as they see fit. If they were excluded from the airdrop, they can appeal. Only the accounts actively participating in strengthening a Sybil attack on Steem were excluded. You cannot include that attack on a new chain if your intent is to create a new chain to get away from said Sybil attack. Pretty basic common sense here and with the appeal process, it was handled professionally. It wasn't just a handful of accounts selected out of spite.
