I think they theoretically should care about the potentially lost revenue from a big chunk of regular bitcoin buyers leaving for a fork coin. I suspect miners make much more money from selling their subsidy revenue on exchanges than they do from selling their fee revenue. And if 20% of bitcoiners stop buying that subsidy, it could be a critical hit for many of them.
