Even the decentralized shit is centralized to some extent.. Almost all of it runs as an app instance on a box somewhere.. Even if it's pulling data from a decentralized chain.. the point of failure is the front end or API or whatever that ties it all in together.

Blockchain is jsut a ledger after all.. Basically nothing out there is a proper decentralized system/box. EVM is about the closest and the specs on it are absolute commodore 64 style specs.
