Not sure I entirely understand where this post is going. What does centralization versus decentralization have to do with a blockchain? Just because Bitcoin and others are using it as a centralized data store for a decentralized currency doesn't mean the blockchain has to be tied to any of that.

I feel like people keep getting really far away from what a blockchain really is (a fancy linked list that can ensure integrity from start to end) and are confusing it for how Bitcoin uses it.

I read it as:

Blockchains(PoW/PoS/etc) are not the solution for decentralized applications because blockchains are a global state and most decentralized application don't _need_ a global state. (Specially non-fintech ones that don't have a double-spend problem like social/websites/photos/etc)

It briefly mentions Secure Scuttlebutt, a gossip protocol that works over meshnets without global internet access as an example of a decentralized technology without a global state.
