If you try to make the argument to say that this is theft,
you can certainly use the same logic to say the Hive fork is theft.
Comparing the fork that created Hive and HF23 that took Steem & SBD from the above steem blockchain accounts is like comparing apples and oranges. All the steem & SBD owned by the accounts of Justin Sun, Steemit Inc. & the people who supported Justin Sun are left in their respective accounts in the steem blockchain. They, just, did not get the equivalent of Hive & HBD in the newly created Hive blockchain like all the other steem accounts did.
You have no idea what you're talking about and if you want to know why you can check out my blog.
If you think Steem HF23 is somehow an "old asset" and Hive HF23 is a "new asset" you are lying to yourself.
If anything, Hive is the original chain and Steem is the fork. Hive retained 90%+ of the layer 0 community.
That is an interesting take but I don't think it holds any water. The original chain is NOT identified by "the layer 0 community" whatever that means. Not to mention all steemians are still active on steem commenting or powering down, etc. I believe the original chain is identified by the brand which is STEEM in this case and we all know which fork has retained the original brand and is therefore the original chain.
