Any assessment aside, you realize that this has nothing to do in either way with decentralization right?
Decentralization is about not having middle men between you and who you want to speak to, or the ideas you want to hear. It's about actually having your own control or direction of your own consumption of content or social interactions. Decentralization doesn't possibly mean that every single person or every project or every business will all get the exact same engagement, number of customers, or outcome from their situation.
What you are suggesting is a value to strive for is "equity" or equality of outcome. Which is a socialist ideal, not one of free choice and decentralization. This is a simple reality of social beings. Literally all social beings actually. This has nothing to do with #nostr or #bitcoin or even humans.
