I strongly urge you to read Vitalik Buterin; he's written a great deal on many core subjects in crypto and is a far better writer and analyst than most.

Bitcoin exists and is successful precisely because miners control authorship of the public ledger. The entire point of proof-of-work is to ensure this. The essential observation, and really the key invention of Bitcoin, is that you ensure that no single party can control authorship to the blockchain unless they control a majority of the mining power, which is very expensive. Furthermore, control of authorship is directly correlated to investment in the network; capital investment in mining equipment, continued investment in electricity for hashing, and value extracted from that in the form of the cryptocurrency itself. In other words, those who are most able to attack the network also have the most to lose by doing so. This is the foundation upon which Bitcoin is built.

Ethereum is a different story because of smart contracts and the potential move to proof-of-stake (Casper). But these arguments don't apply to Bitcoin. There are also people involved in Bitcoin that have political/development disagreements with miners, and thus seek to advocate that 'users' can/do control the network. I recommend a critical reading of both 'sides' and to reach your own conclusions.
