Neither Nebula nor ZeroTier is based on Wireguard.

What they compare in the article are systems that provide some form of ACL, which is why bare Wireguard is not included. That means there are features in the data path that could have significant performance implications versus a simple tunnel. The impact of using ACL features isn't really a focus of the presented benchmarks, but they do mention a separate test of using iptables to bolt on access controls.
