Decentralized ledger.
But who says steemit is controlled by Korea?
As far as I know, it is not a particular country that is reigning supreme power here.
It is whales that act without regard to the development of steemit for their own money-making.

The bird flying high could see far away.
The view from the low point does not see the big picture.
I said not controlled.... I said - centralized Votingpower. When the world will leave your power is also worth nothing.
