How come bitcoin is centralized if it can be revised using fork?

[layoutph]

Anyone can you please enlighten me how come bitcoin is centralized if it can be update using fork by its developer.

What if they modify the bitcoin core codes silently without using the clean code from github for their benefit?

Sorry I dont have a solid knowledge how the blockchain works.

There is more then one definition regarding centralization, but the most common is that you need to have more then half (51%) of the mining power.
A fork is something that has nothing to do with centralization as such. Everybody can fork at anytime, but if you fork and nobody uses your fork, then you forked off to a worthless (alt)coin.
Bitcoin has a problem if we fork into two more or less evenly big coins. Such a fork can be initiated by anyone. You can fork with the goal to be more decentralized after the fork, but if and how you achieve this is a different matter.
This leaves only the question how to make sure that a fork has a clean code. Firstly you need the code to be open source and then you can look at the code and see for yourself if it is ok. If you are not able to do so then you will have to trust other who will check it and say if it is ok. But this is the same thing you do now with Bitcoin since you probably don't understand the code we use know. The difference is that many more people have check the Bitcoin code then any other fork till now or in the future.

even if the code is modified it need to be run by the miners/everyone else, and miners/everyone else don't run bitcoin code that are node checked first

there is no way someone could silently change something without none noticed it, because everything is open source for a reason...besides that if you run a modified code without consensus, you are effectively running an altcoin

usually they say that bitcoin is centralized, when referring to the mining aspect, because almost all miners are chinese big farm

FTFY
however core are using a backdoor exploit to bypass the node consensus by having their codebase only need a pool to creat a block and then 'filter/strip' the data down to resemble something that is then compatible with other diverse nodes, without allowing those nodes to independantly and fully verify the altered transaction type.

if it runs on bitcoins mainnet and accepts bitcoin native keypairs its not an altcoin. its just not sanctioned by the centralist core grew managed by gmaxwell.

this is statistically challengable. the 'china' rhetoric is just social politics played on the lazy crowd who dont check sources. for instance slushpool has been characterised as 'chinese' yet the pool is managed in thailand, stratum servers in different countrys and most of the hashpower is in europe/america

to OP. to answer your question. by people believing that CORE* should be the sole implementation of bitcoin.. they are admitting they have been brainwashed into thinking bitcoin centralisation is a good thing.

an open diverse independent decentralised international PEER network is much better than the core at the top of a TIER network. its that simple

I would view Bitcoin centralisation as being when only a few people control the majority of the hashrate rather than when someone directly controls the blockchain - although a 51% attack is always more than possible in this scenario, which is part of why Bitcoin needs to be spread between honest users.
