Evidence Jihan wants control over Bitcoin.
I have nothing against people making money. I am against people trying to destroy/limit Bitcoin.
The danger here is centralization. Having only a few people controlling mining is not good at all.
There are thousands of miners, working together in pools. So no that isn't a
few people.
Beside, what can you or anyone else do about it? Order the miners to break down into smaller pools of no more than 10%?
