> MetaMask already relies on "Web2" apis to query blockchains
False. MetaMask uses Infura as a default, but you can edit your RPC URL to whatever you want. You can even run your own node and sync the chain if you've got a couple hundred gigabytes to spare (no stake required to run a non-validating node).
They don't have to hit the blockchain all the time. Only when it makes sense. For everything else, there's off-chain signatures. That's the beauty of it. Hey, you don't want to use the chain, just use the sign-in with Ethereum feature, and that's totally cool!
