 They control the domain name. They control where the payment goes. They can choose to forward the payment to you, or they can keep the Bitcoin themselves.  

Users have to trust that they won't decide to rug-pull them, which they can do whenever they want by charging the way they process payments.

Go on, answer that question. I want you to say here that it is impossible for Zeus to change the way they process payments and keep people's Bitcoin.
