Agreed, and I should make it clear that I don't believe a private hosting company should have to serve any client they would rather not serve. Personally, if I were going into the hosting business I would set a policy up front that we're not in the business of moderating content, just because I think taking responsibility for it would be a nightmare. But I'm not in the hosting business and they should be able to do as they wish. Having done this, though, they will be obligated to continue policing the content on their system, or run the risk of being accused of bias.
