Agreed, but consider this: centralisation in this context is intended to refer to the distribution of power and control toward any authority or party, including entrenchment of VC. It's definitely a valid point for something like Solana, less so for Ethereum I feel. At a certain point, the sum of involved interests are simply too disparate to be utilised together toward some nefarious end. Of course, robust on-chain community governance is critical for anything that wants to push beyond the microcap experiment stage that Ethereum was in during 2016.
