Private Stake should never be forked regardless of the situation. The only legit reason is if the private stake owner agrees to it.
I cant be 100% certain but I think that is the total consensus of witnesses. But obviously they also wanted to protect the chain. Think about this justin could have done some incredibly bad stuff when he had all 20 block producers... like really destroyed everything. It's not a matter if we think he would have it's just bad that one person could have. And at the time there was lots of talk of token swaps moving over to tron. Etc
Justin Sun bought Steemit, its his property to do with as he wants. Token Swap is a non issue for me. Anyone can offer a token swap, some may have accepted the swap but I think its likely most wouldn't have. I think the fear built around that potentail swap was unwarrated.
I understand the potential downside of Justin Sun stake but lets be honest here a handfull of people already dictate who the top witnesses are. If the witnesses are serious about the current narrative their pushing (not haven one person with too much voting power) then they need to rework the whole voting system so its more fair to those who don't have a bunch of Steem.
Thanks for your comments @jarvie. I respect your thoughts andopinion on the matter.
