I suppose my preference would be that providers simply build the capacity required to support the advertised bandwidth at 100% utilization. This is similar to what Google Fiber does. They don't care if you use 20GB or 20TB in a month from what I've heard. That sounds optimal in my mind. Underestimating usage and failure to anticipate demand are real issues that major ISPs have to deal with over the long run (off the top of my head AT&T's network problems after the first iPhone was released). I've always viewed these caps as short-term fixes until they figure how to increase their network capacity to support increased use.
