AT&T's terms of service now allow them to immediately terminate the service of anyone who is critical of the company. From Broadband Reports:
"AT&T may immediately terminate or suspend all or a portion of your Service, any Member ID, electronic mail address, IP address, Universal Resource Locator or domain name used by you, without notice, for conduct that AT&T believes ... tends to damage the name or reputation of AT&T, or its parents, affiliates and subsidiaries."
Amazing! By the way, have I mentioned lately how happy I am with AT&T's service? Really..., it is. I mean it.
