Justin Sun purchased the STEEM stake of SteemIt, Inc., the company which owned by far the largest single stake on the Steem blockchain. With it, he had the voting power to put his own Witnesses in control of it. Far more to the story than this, but ... This was the starting point.
Do you mean that Justin Sun pays his witnesses to manipulate and control the press and information?
The "old guard" Witnesses of the Steem blockchain, led by BlockTrades, decided they would simply start their own blockchain, instead of continuing their "war" with Justin Sun.
Does that mean BlockTrades created the Hive blockchain when Justin Sun bought Steemit?
Note: In this "war," a number of prominent Korean stakeholders attempted to "control" the outcome. They failed. As a consequence, they were not allowed to participate in the initial Hive token airdrop. So ... As far as I know (I am no longer participating there ...), they are still active on the Steem blockchain, making who knows what "deal" with Justin Sun ...
You are right. Many Koreans view Steemit as simply a means of making money. Koreans think they are discriminated against on Steemit compared to Westerners. In particular, there are many complaints about Steemit's share distribution.
They believed that Justin Sun would give them an equal share of the Westerners.
Koreans want to make money by running their own closed community rather than talking to you. They want more money than to be friends of 
Unfortunately, they are not interested in or understand the decentralization pursued by the Hive blockchain.
I don't know more about cryptocurrencies than elementary school students in America. ahahaha!
