I have had my upstream filter these ports on me before. They get an angry call right away. I use SMB to mount remote shares, do remote authentication and remote printing. Sure most people do not know how to do this, but I have taught a lot of my customers to do it. Road Warriors love it. They never want to go back to the old ways.
I have worked at several ISPs that found the easiest way to reduce the customer list was to start filtering. A lot of folks do not complain, they just move on to another ISP.
I think SMB attacks are a serious problem and did not have problems at the one place I worked where the ISP started arbitrarily filtering SMB - the only problem was that they gave no warning before doing it.
A good compromise is to notify your customers that you are providing the extra "service" and let them opt-out if they choose.
