There are also a group of people that claims it is a centralized scam. You can also search them on this board. One of the issues is that most of the nodes securing the network are run on cloud like AWS. That makes Ethereum reliant on some private companies.
Who decides when and how EIP1559 is implemented? When to implement Eth2, etc.
AFAIK, there were discussions and voting involved among the ethereum community before the implementation of EIP 1559. Maybe you can call it centralized when it was pushed even though majority of the big miners opposed it.
