Nah, this article is way off base. Web3 is at best a public key signing protocol that authenticates a web client (primarily metamask). You can use this for any authentication with an ethereum-like address, eg: 0x06012c8cf97bead5deae237070f9587f8e7a266d Spending coins is not actually the point. Its to authenticate with a public key, the same way SSH public key authentication works. Most of the time, one should not be spending coins on random websites anyway. This complaint is like saying public key authentication is a plot to put big-PKI in charge. Nonsensical.
