But then, based on my personal understanding, the bitcoin blockchain is completely decentralized as we know it, which simply means that there is absolutely no way for use to wipe off or out a project built on the blockchain, we all will have to bear the effect of their presence on the bitcoin network.
the ledger is decentralised
the ability to self custody your value is somewhat decentralised (yet many prefer custodians centralised exchanges)
however the devs(yes bitcoin is code and code is wrote by devs) is centrally (at its CORE) controlled by its namesake CORE
they didnt choose CORE randomly. they didnt slogan "bitcoins reference client" meaninglessly. there was alot of bribery and sponsorship and campaigning to get that control where other brands get REKT if they dare propose protocol changes CORE dislike
so its CORE that need to fix THEIR bug
