I greatly agree to the fact that decentralization is grows gradually and it gives all participants the room for openness in all areas but the foundation and perhaps the owners have big influence yet I come to infallible agreement with here 🔻
Usually, the founders of the network or their foundation or their companies may have big influence in the network. The network won't reach decentralization until their influence become negligible.
Also, the two Network for the distribution of native coins as in the reward pool if I'm to make preference, I had preferred Proof of Work PoW over Proof of Stake . But I feel that PoW network are slightly into PoS where your reward isn't based on the quality of your work but just do something but since you have big stake, your reward is very high. I saw this in other blog sites where a single flower picture or a simple sketch would earn hundreds+ dollar while a very detailed and informative article gets almost nothing yet such a network says it operates on Pow consensus mechanisms and I just wonder but these are still on the influence you mentioned above and borrowing from your words, until the influence of the foundation or owners are brought to almost nothing pure decentralization might not be fully achieved.
Decentralized technology is still on its developmental stage I'm sure these aspects would be taken care of in the future.
