Yet, the way Web 3.0 works in practice is with a browser extension (which Reborn basically integrated) that does http API calls to a centralized 3rd-party server.

So while they market decentralization and trustlessness, they are one server-compromise away from getting fed a completely false view of Ethereum's blockchain state and losing all their funds.

If that's an attempt on web 3.0, we might as well just skip straight to web 4.0.
