Tess of millions of dollars? If that was the case the price would be 100$. There was no liquidity on the exchanges. It might 'felt' like crazy amounts were spent but 2-3 mill Steem brought into the platform by Justin and a couple more millions by average users certainly isn't tens of thousands of millions.

Plus, do you remember the official announcement?

The only accounts who will not be included in the initial airdrop are those containing the Steemit Inc ninja-mined stake, and those who actively contributed to (and publicly declared support for) the centralization of the Steem Blockchain

The Hive airdrop will only be performed on the current version of the Steem blockchain (as of the date of this post). Any "emergency hardforks" performed prior to the airdrop will not be eligible. Further, any exchange that participates in such a hardfork prior to the airdrop date will null and void the ability to participate in the airdrop for its off-chain balance holding customers.

There is no way he can affect governance ever again. He might possess 3-4 mill HIVE but that's all...
