The miners do have the power to hard fork - they can choose to run a node that implements the fork > A hard fork is determined by the users, who have to upgrade their software. Who are 'the users' here? Light clients? Users of wallets? None of these have the power to adopt a fork, soft or hard. The collective action of the miners (or validators) defines which chains still retain liveness. For example in the hard fork…
Anyone who runs a full node can decide any set of rules they want to follow. You can incentivize miners to mine on your fork by providing block rewards. If you pay people to do something, at least some of them will. The ETC fork would have been successful at any non-zero support level from people with the ability to mine. And since any CPU can mine (just inefficiently), any fork can get a mining baseline. That may no…

It would be economically irrational for people to send transactions to a fork with a single miner since that miner could unilaterally rewrite any transactions as they see fit. This is why I think miners have the ability to control forking.
