> But this fails to hold true for general purpose chains acting as a VM, including the front-runner Ethereum. Ethereum nodes can in theory filter modifications to the smart contracts they execute, but in practice, node operators have no reason to inspect or reject these upgrades, because they have relatively little stake in the success of individual contracts or their ecosystems. If an owner of a smart contract publishes a new change, nodes will mindlessly run it. Ethereum is blockchain AWS. This part does talk about Ethereum itself. It's just a conflation that, I agree, the author probably didn't intend, but nonetheless demonstrates the lack of understanding.
