...Decred ... users have the power to vote against the (illogical) decision of miners
can you explain a little more about how users vote
But in bitcoin, users do not have any power to directly influence decisions on bitcoin blockchain level, miners have total control here.
the users in bitcoin are defined by Nodes and if you run a node you will have an influence and can have a say the future of bitcoin.
Yeah mining is done by miners, they are the backbone,
no they are workers on the network, or simply employees. the nodes are the backbone. if miners change something and majority of the nodes reject it then they have mined a useless junk because the network didn't accept it.
i believe UASF is an appropriate example in this case here.
