Cryptography where users have to trust the server is a bit funky

Pretty interesting. It is a rabbit hole, you say well I dont trust this so I secure it here, and then you have to trust the next layer down. Eventually you have to have some level of trust. But I think its pretty cool none the less.

Neat idea. Kagi is doing something similar for search, where they can verify that you have paid for the privilege of using the service, but can’t link your actual account.

Lots of VPNs do that.
