That's not how Bitcoin works, and the article doesn't make any claim to the contrary. Neither Bitcoin owners nor Bitcoin miners control the rules of the network. If they were to unilaterally change the rules, their (now forked) Bitcoin wouldn't be accepted by sellers any more than I can use Monopoly money to buy a meal at McDonalds.
Contrast with Ethereum, which with its Proof of Stake switch does give some level of control to Ethereum holders.
