I am not certain whether he will dump Steemit or when he would do it.

The question: Does he see Steem blockchain as a useful tool in the long run?!
He had made lots of enemies already. People now know what he’s really like as a businessman.

Will those remaining bloggers continue to play his game? There are still many big accounts with lots of Steem. If half of them start powering down and get out, what would happen to the price of Steem.

Is it worth his while to continue to prop up the blockchain for the remaining bloggers?!

So, if people stop blogging, there is no income stream or much reduced income stream. How could Sunny make profit out of the company?

There are so many questions with no answers.
But he would be able to obtain all the sleeping accounts’ Steem after the owners have left.
The blockchain may be intentionally degraded so that people could not move anything or do anything. Natural degradation would make him look better in public.

Of course, I may be wrong in my speculation.

Wait and see.
