In France, Free (one of the major telcos) has done exactly that. They block ads from the router that they give to their subscribers.

I guess they may be doing that to save bandwidth... They also have a tendency to offer features that few of their subscribers use, or even know about (some of their routers come with built-in VPN servers and torrent seedboxes).

If they do this wholesale, they should probably block this at their BGP routers.
