miners are sufficiently smart to recognize that they don't want to be part of a mining poole that acts so recklessly and takes stupid and unjustifiable positions.
You write as though you are under the impression that more than 10% of Antpool's hash rate isn't owned by a single business.
What one miner decides is what 90+% of Antpool's mining power will do. And I'd bet on 90% of the stuff he DOESN'T own just sucking along for the ride.
