What happens to the people who are left?

Not everyone knows about PHORM and the deals they are trying to do, so once everyone else has opted out of BT and VM, there will be so little traffic (but fabulous speeds) that it will be quite easy to identify who is looking at what for the customers left. This is starting to look like the herds of wildebeast heading for the crocodile infested river. Most will get across unharmed, but if there is only one or two, then they are eaten. Those remaining with BT or VM will get all the ads, because why be selective to only a few. However I have noticed a few links to the debate appearing on the BBC website (who as normal are trying to be "neutral" in any debate, but not investigating the problem).
