The Service is a consumer grade service and is not designed for or intended to be used for any commercial purpose. You may not resell, re-provision or rent the Service, (either for a fee or without charge) or allow third parties to use the Service via wired, wireless or other means. For example, you may not provide Internet access to third parties through a wired or wireless connection or use the Service to facilitate public Internet access (such as through a Wi-Fi hotspot), use it for high volume purposes, or engage in similar activities that constitute such use (commercial or non-commercial). If you subscribe to a Broadband Service, you may connect multiple computers/devices within a single home to your modem and/or router to access the Service, but only through a single Verizon-issued IP address. You also may not exceed the bandwidth usage limitations that Verizon may establish from time to time for the Service, or use the Service to host any type of server. Violation of this section may result in bandwidth restrictions on your Service or suspension or termination of your Service.
Well here's how they can artificially cap your unlimited plan. 'may not exceed the bandwidth usage limitations that Verizon may establish from time to time' or 'use the Service to host any type of server'.
Plus the AUP allows them to nab you from anything from off-topic posts (Attactment A.2.e) to hitting IP's in embargo'd countries (cuba, sudan, etc) Attactment A.2.l. And unless this somehow excludes personal server, my guess is tons of users are violating some part of the ToS.
