Now Sun says he just wants to sell it and profit.

With all the plans they thought they'd achieve for steem as written on their post? Not likely he'd want to dump. He's not that stupid. But of course, as an investor, and like steemit inc had done many times in the past, he'd sell off some to take profit. This is based on his understanding that he bought a company for the sake of developing it for profit in the long run. Steem price prospering means the whole chain prospering. Justin didn't spend $50M to give his steem away. No one would agree to that.

He has used it to completely centralize governance of the blockchain - colluding with exchanges, potentially criminally (IANAL).

Because our witnesses froze his stake.
We really should stop using this as a premise for justifying whatever is going on here now. We froze a businessman's stake out of impulse, without a conversation and we pushed him to react. Whatever he did, we made it happen.

Well, we are entitled to have different views on this subject, and i respect that we could voice our opinions without any hostility. After reading this post, I fully support Hive account@glory7's views and decision in this matter.
Steem on, man.
