Hand for a hand analogy is not comparable. This is not a situation where one does damage, the other does damage, we call it even (the premise of the idiom). I expect I don't have to explain that to you should you read again.
I am very much in favour to welcome these folks warmly if they want to join Hive.
Well, this is leading to a very circular argument that has been exhaustively debated already, so you can get that info from other debates, but nobody is banned from Hive. All are still welcome there, warmly or otherwise (being warm is not a requirement in a decentralized environment).
The only difference is the ones who were actively acting against decentralisation don't get free money from their enemies. This seems daft to me.
Imagine that in the real world:
'Hey you just oppressed and colonized our nation, so we moved away to another land. Here, take a bunch of our wealth as an incentive to join us here, too'.
As I've said plenty of times, I don't necessarily agree exactly how the specific code was implemented, and there were genuine mistakes that are to be corrected (it happens all the time). Those who had innocent intent can get their stake in the next hardfork, and those who did not, will not.
If there should be a few collateral who cannot get their stake and had innocent intent, well, they aren't losing anything. They still have their steem, and they also gain a free Hive account.
Everybody wins, to me.
