I don't get what you're saying. Are you saying Bitcointalk is the only forum that can exist, that anybody should ever use for cryptocurrency discussion? Can't a community have its own private, self-hosted solution where the lead developer has administrator roles? Do you really want to spend your days looking at this old and crusty forum software? You don't have to use it, Discord and Reddit aren't great for long-form, productive discussion. If someone has to make an account for a forum, that's a proof that they care a bit more than the average user. There are plenty of self-hosted forums for Ethereum.
