Suppose for the sake of argument that CF stopped doing business with DS because those enterprise clients that comprise the majority of their revenue were threatening to drop CF. So what? CF is a business and sacrificing their biggest customers for the sake of a nazi website is not a great way to stay in business. Really though, this is just splitting hairs. The difference between "CF was angry that DS claimed CF supported their views," "CF was being pressured by its biggest and most valuable customers," and "CF was concerned that keeping DS as a customer would negatively impact their IPO" is just a small detail. The point is that having DS as a customer is bad for business and CF, like all those other companies, decided that it was time to protect their business. What specifically prompted that decision is not too important -- it was just the straw that broke the camel's back. Don't play coy about the nature of your site. Almost nobody actually wants websites like DS to exist and DS is toxic to the brand of any company that does business with it. The existence DS is merely tolerated as an unfortunate consequence of free speech, something which is outweighed by the various benefits of a democratic society. Your ability to remain online at all is tolerated as an unfortunate consequence of the free and open nature of the Internet. Maybe you cannot see that, but it's not hard for the rest of us.
