We discuss these limitations as if it were anything other than expecting someone else to subsidize our bandwidth consumption. People who run afoul of personal use restrictions know exactly what they are doing, and that they could never afford the bandwidth legitimately. They lead the charge against metered usage, then act like it's unfair that ISPs court the low usage customers and cut off the people abusing it. If you want fast connections with no caps and no restrictions then pay per MB. If every bit transferred means dollars the ISPs will be happily courting home server users.

A fat person may eat 2-3 times what a normal person does. Not 10,000 times. The analogy is about abusing normal expectations. You are trying to make it fit too tightly. If you really want to extend it to 24/7 access to a buffet it would mean taking up all the plates/silverware so no one else can eat there. Then becoming indignant when asked to leave 'you said it was unlimited!' But I have no desire to play analogy ping pong.

All I want is for the limitations to be upfront. And if there are 'overage' charges they shouldn't be priced orders of magnitude over cost.

Someone that uses a lot of bandwidth isn't doing it to be a jerk. And if they inconvenience others the network is frankly set up badly. Normal users will saturate a connection some of the time, and networks need to handle it. And if a network can handle saturation for one hour without problems, it can handle saturation all the time without problems.
