It's hardly 'evil' of a company to contact high bandwidth users personally and ask them why they're doing it, rather than just randomly enforcing bandwidth limits, STMs or FUPs.
If you talk 24/7 over the phone no one will ever call you and ask why. It is very simple, since BT will make a fortune out of you and you hardly stress the network. With xDSL however, is like having 20 calls at the same time which you pay a flat rate for.
The problem with ISPs is that their cheapo hardware and links are overloaded heavy. THe business customers (paying thousands of pounds) keep calling in crying about congestion on the network and the tech people shape home users to ease the load.
It's all about marketing double digit connection capacities (not speed, as they wrongly advertise. speed goes with delay) and then hiding behind 6pt character fair usage policies.
