Steem hf23 and Hive hf23 are pretty different animals for one key reason: Hive never removed any funds from any wallet. It created a new asset

I know it's hard to believe, but it's true. Go look at the blockchains

A new asset was created on steem by doing some maths on steem. The steem witnesses don't know how to process this new asset, so they ignore it. Don't take my word for this, the blockchains show it

Identical blocks. This is a pre-fork block. It's is produced by a Steem witness. It did math against the steem ledger to produce balances of an all new asset. Obviously if that code ran on steem and moved anything, steem users would see their balances gone from it... but they don't. Steem just doesn't show the deposits for the new asset because it can't

The creation of the new asset would have been ignored and looked like nothing ever happened, but for one key thing - the steem witness received it, and gtg started from that point with a fresh balance of a new asset on a new chain

It might be hard to fathom - but look at the blockchain. No assets were moved from any account at any time as part of the Hive hf23

And that makes a pretty big difference when we're talking about theft
