OpenSea takes the blockchain data, filters it and augments it with their proprietary data. Which means that as a user I may buy an NFT that OpenSea is filtering and which therefore is useless on other sites.
There is nothing inherently special about blockchain that prevents centralisation or allows you to have a trustless ecosystem. At some point I will trust Metamask with my wallet, Binance for my trades etc.
