I agree with them (Score 4, Insightful)

I own a small ISP, so I fully agree that it's within ISPs rights to limit the connection to only those who purchase it for consumer grade services. If you're a business or reseller customer, you can purchase a T1 or higher cost/bandwidth circuit and do whatever you want with it. If a ~$50/month residential user ends up giving his access to the whole neighboorhood, there won't be any money to run the services. We all know free Internet doesn't work. So suck it up and pay for your own service so you can have reliable and decent service from your providers.
