Yes, bitcoin is not decentralized.
1- as you may have seen binance was about to ruin the whole crypto market in 2019 when they wanted to reorg blocks to recover a hacked 7,000 bitcoins.
binance was not about to nor wanted..
in the space of 8 hours of social drama 4 years ago binance said it was approached by other groups of services and pools asking binance does binance want to re-org.. binance released a periscope video just saying
others asked him if they should help.. so not his idea..
.. 8 hours later he made another tweet saying he has no plans to do it as it can cause many bad effects..
so even though its been 4 years since that single afternoon of non events, just social gossiping/drama.. it seems people here today still thought it was a thing.. its not. was not
if you however do want to talk about some real centralisation. look at the CORE of the protocol. they named their brand that for a centralist reason. and any other node brand trying to offer the same features(protocol change proposals) will get REKT
do some better research.
also mining pools do not code the rules/protocol, they follow the rules or get blocks rejected. they have been found to have their blocks rejected many times if they even tried to go against the code.. so if you wish to look at the centralisation. look who actually makes the code changes(has the real power)
binance and mining pools do not write the code nor have they done reorgs.. but one group has rejected block, mandated changes to the protocol a few times now
Foundry is owned by DCG which already tried to change Bitcoin's consensus rules with Segwit2x. That didn't turn out to well for them thus reinforcing Bitcoin's decentralization.
actual events were that DCG were working WITH core to get segwit activated using a flag event to get segwit active with a
empty promise of a 2x base block increase ['sometime'] later. their flag event did activate segwit. so their campaign worked as core and DCG wanted. but it was the 2x part that was never wrote into code at the time and has since never been wrote into code
yes blockstream(cores sponsors) was funded by DCG
and to add more detail to that drama. the other
pretend opposition to cores segwit was bloq. whom DCG also has in its portfolio..
