I'm not sure why you're being downvoted (language maybe? But we're all adults here) but you're exactly right. Fastmail is a company that provides a service for a fee, it would be insane if they didn't have a TOS enumerating their rights regarding their customer relationship. If they didn't have the right to terminate service, the customer could do whatever they wanted (use the service to send out spam or engage in illegal activity) with no risk of losing service. If GP wants an email service that will let them sidestep the law, as you said, they can roll their own. I can't think of any other reason someone would be turned away by a sensible TOS.
