There's Google One VPN (which uses blind signatures for access tokens) as well as iCloud Private Relay (which leverages nested encrypted channels terminated by a different entity than the one that receives user-side traffic, as well as blind signatures for authentication if I remember correctly).
That said, it's definitely nice to have alternatives, but as with all VPN services, I'd be cautious – the proposition of "perfectly anonymous network access" attracts a lot of attention, not all of it beneficial to the product/project.
