Naw social order is more important for a POW chain.
BCH never did get a mining block tax b/c of social outrage would bankrupt miners.
Miners are always in fear of a GPU mining fork or even a soft fork version of it.
GPU based forks are the worst for Asic coins. Would crush them.
Could it split the coin? Sure but the mining part isn't that important as mining aren't holders of the coins rather powerful workers. No owner of an asset would be affected supply wise(price wise....) unlike POS coins.
Btc is getting heavily based in America once again though I think their like atleast 10% in new America based hashpower.
Added the fact second layers are freer from most miners control so even if they start censoring txs, second layers can still function.
Should be noted though many other people would say Bitcoin is under dev control not miner control if that is the case in your viewpoints-well there you go no worries about miners attacks.

Another thing I guess I could point out that if fees do not make up the cost of mining: there are talks of either accepting higher number of confirmations for each onchain tx and/or small block reward inflation(as many econ argues might be ok)

The hope has always been more fees money and more efficient/cheaper miners and power sources-bch and btc.
The backups I mentioned above are backups solutions in work
