ON WHAT IS DECENTRALIZED

Summary from the TLDR Crypto newsletter

This thread explores the current state of decentralization, emphasizing the contrast between permissionless blockchains like Ethereum and websites like OpenSea. Any website can choose whether or not to display an NFT, but they cannot modify the NFT itself. Most Layer 2s are still fairly centralized and controlled by a few parties. Decentralization will likely improve in the coming years.
