In your opinion, is it a matter of Bitcoin miners not caring, or is there something else at play?
Just because mining pools give individual the miners to choose Bitcoin Core and Bitcoin classic, does not mean they will be switching over in droves all of a sudden. That statement is only reinforced by the F2Pool mining statistics, as only a small portion of miners have diverted their hashpower to Bitcoin Classic. This begs the question as to whether Bitcoin miners care [enough] about the difference between both solutions to risk their steady earnings or not.
