I don't think so - I'll go with mlmclaren on that.
The 40/20 was a very strange beast for a budget-priced ISP, unless they got some limited period high discount on 80/20 to provide it. Even that's unlikely as they must have picked up tens of thousands on it, most of whom will stay for a long time.
The 40/2, as someone who had a brainwave suggested, may be the result of analysing the customer base and upload usage. If that were the case, I wouldn't be sure they've thought it through. At signing up time, which is all that matters, the natural preference is to go for the highest speeds you can get.
The counter-argument I nearly put to that is that possibly few (non-forumgeeks) look at the upstream speed when signing up. The reason I don't advance it is that it would remove any reason for offering 40/20 in the first place.
Oh wait ...!
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
