Much of what you say is true. If you were excluded, and you were not a part of some grand conspiracy to centralize the blockchain, would you want to continue with Hive? Bear in mind, that you were just excluded from the airdrop, and that exclusion was based on failing to unvote. Do you think the existing witnesses will be likely to evolve the blockchain in such a way where witness votes decay? They'd be imposing upon themselves an uncertain future and signing up for a lot of extra work with regards to campaigning.
