"We have a business to run, and a duty to our shareholders to maximise the profit/mitigate the loss from it."
Saying that something "is simply untrue" and then justifying it with theoretical calculations isn't really the way to influence people. As I have said before, the vast majority of broadband users will never approach a 1Gb a day downstream file transfer - so where's the problem? Bandwidth was always going to be the ADSL issue, and it's no surprise to hear that some people are transferring huge amounts of data - other countries have experienced the same thing. Nobody's turning low bandwidth users against high level users - that's a tad fanciful. What's happening is that some people (present company excepted naturally) are trying to whip this up into something that it isn't. The words "Storm in a teacup" spring to mind.
