terms of service

I'm attempting to sign up for new fiber service and as part of the terms of the agreement Xfinity wants us to agree to a third party "terms of service" with Peacock.  We have no interest in Peacock, no intention of using Peacock, and I'll NEVER agree to a third party inclusion in a two party contract.  Its like buying a new car and the dealership wants us to agree to Exxon's terms of service.  Reading through Exxon's terms, we realize that purchasing gasoline from Mobile or BP violates the "terms of service" making our new car purchase subject to repossession.  I simply want 1GB fiber service and a contract between the two parties involved.  Simple.  Straightforward.  No third party involvement.  How do we get this?
