Yes, you are definitely right. All the previous airdrops made as a promotion over Ethereum blockchain will be shifted to Telos Mainnet.

The first part of the airdrop, the one based on the Telos original snapshot is already done and I didn't write about it yet. But when I do I will call for all the steemit users that recived CNT tokens in the past (on Ethereum blockchain) and re-drop the Tokens over Telos mainnet.
