They don't speak for Bitcoin. You still have avoided answering my question as to who you think they are.
I will tell you that that limit
*could* be changed. It's only part of the protocol and if a majority of the network wanted to it could be increased. I don't think that is likely to happen.
It is however completely ludicrous to say that "Bitcoin promised" anything.
You are also completely missing the point of what Bitcoin is about. It's not about 21 million coins it is about trust.
https://nakamotoinstitute.org/bitcoin/#selection-49.4-49.211What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party.
