Justin’s stake is unfrozen. It has been since he first took over the witness spots with the aid of exchanges. Pretty much every witness has assured him it will not be re-frozen and are asking him to step out of governance. However so far he seems to be digging in and powering up more, despite saying he has no interest in governance, and sadly his witness servers are still not even properly configured with a price feed, showing the Tron engineer’s lack of understanding or concern for the Steem blockchain.

edit - I also believe the only exchange still voting/not powering down is Poloniex, which of course Sun has some ownership stake in and thus more control. We've been at your listed conditions for talks beginning for days and I think talks have stalled and folks are just entrenching their SP. Steem is swimming against the tide in terms of the big sell off in crypto the past couple days, all due to "arms race buying" I believe.
