The point is that you must expect inbound traffic to any prefix you advertise to the outside world, even a more specific announcement is also being advertised. There are legitimate circumstances where an ISP would prefer the super-block.
It's not about the business reasons for wanting it, it's about what the router does if it's presented with the options. Like I said before, you can do things to your network to prevent your router from installing a longer prefix. But if you do not, the longer prefix will always be installed and used, first. Mark.
