Does MEV Mitigation through Private Pools Compromise the Decentralization Ethos of a Blockchain?

Some argue that private transaction pools compromise decentralization because they introduce a trusted intermediary (the block builder/relay) that controls the ordering and inclusion of transactions, potentially leading to censorship or centralized control over the block-building process. This contrasts with the fully transparent and permissionless nature of the public mempool.
