ISPs can only advertise based on the speeds their customers receive at peak times, this requires the router to run some software that the ISP can use to run tests to etc. It also means that support staff can see if everything is connected via Wi-Fi with poor signal strength when people phone up to complain about speeds.
99%+ of the country probably don't know what a router is, by giving people the "save £2 a month and don't have a router" option you will get people opting for that instead and then taking up hours of time when they call in for support.
I'd like to be able to opt-out mainly from an e-waste perspective as I can't see the cost savings being significant, but it's fair that ISPs won't deal with you if you're not using the router they supply and you're having issues.
A lot of this hassle could be solved by just giving people a bridge mode though. Leave the ISP box there for the speed tests and the VoIP or whatever, and pass the public IP through to one of the LAN ports on DHCP so that other things can be used without loads of messing around.
