I suppose it is more of the threat of a hard fork which cuts out the miner's is what would persuade them to not abuse their power.
I've seen no evidence of miners "abusing their power" - if anything the miners (at least pools) have tried their hardest to not get involved with the politics and just support the future of Bitcoin (which makes sense for them economically).
It is the exchanges (and mostly just American ones) and some of the devs (ex-core) that have been the cause of all the troubles so far (and in the case of devs that seems to be mostly about ego rather than anything else).
