Dear @sumit1998
Your title suggest that you consider recent purchase done by Justin Sun as an attack? Wouldn't you think that he have spent enormous amount of money and so far he isn't showing any real act of hostility towards our community? If he would "hi jack" then he would get pretty much nothing for few million usd which he spent.
Considering that Justing is a business man in the first place - I would assume that he will treat Steemit and it's community as an asset. Asset which will bring him profit - instead of losing money.
Entire STINC team seem to be very happy with this solution (especially comparing to @Ned being in "charge"). I myself decided to be quite optimistic about the future.
ps. did you ever consider setting up anything as your profile picture? right now your account does look like some bot / someone who is very new to steem blockchain
Yours, Piotr
