I agree with everything that you are saying. We need to ask at every step of the way does this make things more centralized or does this make things less decentralized? Money grows exponentially in the dollar economy, so its not an accident that we live in a 90 / 10 world. Even within the top companies such as in the S&P you see are starting to see consolidation and the FAANG stocks are a perfect example.
If there is even a slight bias in the reward mechanism, which articles get selected for top billing on front ends, or in the governance of the platform then you will see consolidation. Every blockchain should disclose their centrality metrics or wealth distribution metrics. That way people don't have to speculate and it sends the message that decentralization is a core value of the chain. You are what you measure.
