No, I care about liquidity, but I do think it's okay to banish an exchange that acts irresponsibly or one the presents a serious conflict of interest, especially Poloniex, considering Sun owns a stake in it. That exchange, plus his stake is far too much power. I can accept a little LESS liquidity if it means taking exchanges out of the staking equation. We already have other exchanges hopping on board.
I agree his Steem should be unfrozen and that we have to contend with the faults of dPOS and I can safely say that as much as the witnesses jumped the gun, Sun has blasted trust out the window by using the exchanges to vote himself into power, which is what I think he would have done to begin with. He's demonstrated that he is far less trustworthy than he proclaims. He claims to want to protect the "sanctity of private property" but is more than willing to violate EVERYONE'S if it means getting what he wants. He claims to not want to be involved in governance, but won't remove a single sock puppet.
I'll believe he's willing to give up voting rights the minute he relents on some of his sock puppets. The witnesses have already said they'd unfreeze his stake, so we need to see him act in good faith to let the witnesses govern. They've been voted in and we need to see it through with them at the helm for now.
