Any changes to BTC require broad consensus of all participants (nodes/miners/users/exchanges/etc). No one can unilaterally make changes, when they try they end up with forks like Bitcoin Cash. Just take a look at a change like taproot which almost everyone agrees is a great change, the rollout has been very conservatively done despite not being controversial at all. The flip side of that is Bitcoin is very hard to change which frustrates many of the people who go buy altcoins, but that's a feature, not a bug.
