for bitcoin's sake, i hope that never happens.
one of the reasons bitcoin is so superior to altcoins is its decentralized and consensus-based development process. unlike ethereum or ripple or bitcoin cash or BSV---which have small numbers of extremely influential developers and decision makers who can economically coerce users into following their forks---bitcoin development is merit-based, consensus-based. with bitcoin, there is no vitalik buterin figure to pressure the network into accepting the ethereum foundation's roadmap.
i believe this is one of the reasons satoshi left and also why he/they will never return.
I completely agree with your opinion, and some people should try to better understand what is Bitcoin. Strength of Bitcoin is not in one person, but just the opposite - we are all reason why Bitcoin is still live and it is going forward.
The most obvious example of centralized
bitcoin is Roger Ver or CW Faketoshi shitcoins, and this is probably main reason why Satoshi Nakamoto is decided to pull back and remain anonymous.
It would also not be wise to appear now or ever, because it would most likely end up as Julian Assange.
