Blockchain is Not Trustless or Decentralized

If you ask the average person in the blockchain industry what the benefits of blockchain are, they'll probably mention trustlessness and decentralization. Three modes of decentralization are described: Architectural, political, and logical. Blockchains like EOS are extremely centralized, having just 21 nodes. But if we look at big tech players like the FAANGs (Facebook, Apple, Amazon, Netflix, and Google), they have many, many servers that are highly distributed. When a new transaction is made, the changes are replicated across the entire network, updating every node.
