I think that Sun's account on Steemit has been either hacked or someone else from Steemit Inc has access to it and wrote this bullshit.
It's hard to believe that he would write such vulagar and ignorant bullshit after the live talk with witnesses just over a day ago. This post appears like he didn't listen to them and all he said there was bullshit, and he has not made an effort to explore and understand further how STEEM blockchain really works.
