This is actually an argument that is sometime raised in regards to net neutrality. The difference between an ISP and a web host is that the former functions more as a utility (the debated common carrier classification). If they are a common carrier, the analogy would be the ISP is the power company and the web host is a land lord. The land lord can choose not to rent to someone for any reason other then the person belonging to a protected class. But the power company can't turn off their power as long as they keep paying. The distinction makes sense because you can find another land lord to rent from, or buy your own house (as you can find another web host, or become a web host). But you still have to get power from the, usually one, local electric company (as you have to get a connection to the internet from your, usually one, local ISP).
