In defense of the tier 1's it's not as easy as it looks to run BGP with the lower end business customers. On the technical side the edge boxes and links to them would be as overloaded with routes and peers and all of the other PE boxes in an ISP network. Not to mention the changes in routing policies and addressing schemes and the general operation of the service. This obviously isn't the case for every ISP, but I can understand why it's not popular.
