Ok, but what does congestion mean? Not enough supply for the demand.
If there was plenty of data to go around and no bandwidth problem, the hogs wouldn't be negatively affecting the experience for everyone, and wouldn't be called hogs, as there would be plenty of bandwidth left for everyone else. They would just be users who use more data than others (which by the way, they paid for).
If there wasn't a bandwidth issue, why would AT&T need to throttle people's connections?
You don't understand how the system works.
The system can never handle 100% of its theoretical capacity. It would break down completely. As you get closer and closer to the theoretical capacity, performance gets worse and worse - latency increases and the requirement to resend data increases. So, for example (these numbers are made up, but they demonstrate the issue):
If the system is operating at 10% of theoretical capacity, latency might be 10 ms and only 0.1% of packets must be resent.
If usage increases to 50% of capacity, latency might increase to 30 ms and 2% of packets must be resent.
At 80% of capacity, latency might be 100 ms and 10% of packets resent.
At 90% of capacity, latency might be 300 ms and 20% of packets resent or rejected (this 20% must obviously be included in the 90% of capacity figure).
At no point can one say that there is no more available capacity. But clearly, the data usage that drives usage to 90% of capacity is causing a significant degradation of service.
AT&T's position (and the other telcos, AFAIK) is that the system is getting up to a utilization level that causes degradation of performance. Allowing a few ultra-heavy users to continue without limitation will cause even more severe degradation for the other users. And when you consider that the top few percent of users use a huge percentage of total data, it can have a serious impact.
