You are correct, in all regards. (I also pay automatically, making such methods of informing the user rather ineffectual.) I am not clear that they are required to inform you. The current terms state, > Your Service is subject to our business policies, practices, and procedures, which we can change without notice. but go on, > WE WILL PROVIDE YOU WITH AT LEAST 30 DAYS' NOTICE OF ANY CHANGE WARRANTING CANCELLATION OF THE AFFECTED LINE OF SERVICE AND YOU MUST NOTIFY US OF YOUR INTENT TO CANCEL SERVICE WITHIN 14 DAYS AFTER YOU RECEIVE THE NOTICE, OR AS OTHERWISE PROVIDED IN THE NOTICE. It is not clear to me how the statements "We can change without notice" and "We will provide you with […] notice" are not contradictory. > This is all spelled out quite clearly on their website when choosing a plan I only see that screen if I explicitly click on "Comparison chart"; if I simply select the plan, I never see that; nonetheless, I concede that it is there, if hidden. Since finding a hardcopy of my agreed terms is utterly hopeless, I looked it up via the Wayback Machine: At the time that I signed up with the plan[1], it was "Unlimited" with no qualifications, and none appeared even in the fine print, AFAICT (correct me again, if I'm wrong). I'll concede that the terms allow changes at any time, and while it may be within their right to do so, I still find it morally objectionable; AFAICT, such terms exist in nearly every contract a person agrees to these days, from renting to cell phones to ISPs; what choice have I?
