Because they aren't so passionate for decentralization. They just wanted a new king.

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.

It has everything to do with indifference to decentralization, if the money in the system goes to rich celebrities as homage, rather than developers, creators, and service providers as payment for goods or services rendered. Then the producers go to those celebrities for income, turning them into supplicants to centralized monetary dispersal, rather than entrepreneurs in a free market, selling directly to consumers and competing on quantity, quality, and price. If the money is centralized, then the power is also centralized because the decision-making is centralized.
