The world is watching now. So you have to be much more careful with your actions.

Justin may have enough SP to take over the witnesses but probably won't now because he would loose most of the community (the value) and look bad to the world. The steem price would crater.

The exchanges won't vote anymore as they NOW see just what they steped in and they want out. If they vote again... The crypto community will put them out of business, however it may already be to late to save them. Public opinion is already super negative.

And I think BOTH are just now realizing that even if they could pull a hard fork you can't safely (maybe even legally, because of notification requirements) make a change like that in 3 days. Odds are super good that if you a rush change like this, you will crash the chain.

Now that the crypto world is watching that would be disastrous to his reputation.
