Three pools (dwarfpool, ethpool/ethermine, and f2pool) control around 64 % of the hashrate currently.[1] I don’t know how many people are behind these organizations, but their vote, if coordinated, would be decisive in whether any kind of fork takes place.

Correction: ethermine, much to my delight, has enabled individual voting. (I don’t know about the others.)

Where did you get the idea that Bitcoin is mined by less than a dozen guys in China. This is absolutely false. There are major miners in the US, Georgia and elsewhere.

Around 70% of the hashrate is controlled by 5 Chinese-controlled mining pools.

the hashrate chart.... ? the recently mined blocks perhaps?

what they wrote was only BARELY hyperbole, barely.

It's much worse.
