DO USERS CARE ABOUT DECENTRALIZATION?

Summary from the TLDR Crypto newsletter

Though it may not be explicitly stated, users care about a chain's safety and liveness. In blockchains with few validators, there are slim guarantees about uptime or a strong, honest majority. Users have demonstrated their preference by quickly switching from sidechains and alt L1s to L2s. Low fees and a great UX are important, but are being built up to ensure sufficient decentralization for Ethereum.
