Re: Hope they win.
In BT's case, they also claim they put a Quality of Service policy on the router so the home network always takes priority over the public one and therefore your service shouldn't be impacted.
And do you get any way of verifying this? Sounds like a great deal for BT as most people won't notice this is part of the deal; if they do, won't understand the implications of this; if they do, won't be in a position to monitor their service based on overall usage; if they are, can be brushed off with a quick "Oops! Our mistake! <CLICKETY-CLICK> There, fixed that for you."
ISPs in general have a history of selling customers one thing and giving them something entirely less. Why would there be any expectation that things would be different in this case?
