(BTW, this story isn't about "this mess". I probably should not have even used the name Steem in the post.)
As far as what chains are called this really isn't determined until after the fact. In the case of Ethereum "forking out" the "DAO Hacker", the chain with the modified consensus rules became ETH and the chain with unmodified consensus rules became ETC, but things could have gone the other way, too. Programmers like Alice don't get caught up in political/marketing debates over things like names.
You can use whatever names you want but this story is obviously related to the current events happening on the Steem blockchain.
That's fine for Alice, but in reality names are very important. What's going on in Steem right now is really more about people and reactions than anything technical, and at the end of the day it all really comes down to the naming. Steemit only felt threatened because they thought their stake might be forked out of the Steem blockchain. If the "Alice" in this case had simply said she would call her fork something different than Steem, there would be no threat, and no "mess".
I know your story isn't "about" this, I was just pointing out how it relates to the current situation on Steem and how things could have gone differently by just presenting the same thing in a different way.
Related in a sense, but really only because of the topic of forking. Clearly this post is about forking, that's in the title. Pretty much everything else in the post is different.
No doubt that is often the case.
