Most people find it OK until it is their own speech being silenced, and then they have a problem. It's one thing when NAMBLA is banned from a social networking site, and another when your anti-war group is banned. That aside, there is an important difference between corporations and the government: corporations do not typically have the power to imprison or kill people, and when corporations want to impose a penalty they must ask the government to do it on their behalf. GoDaddy can refuse to provide service to nazis, but cannot do anything about nazis choosing some other registrar. A government can imprison people for running a nazi forum, even if the nazis set up their own registrar and maintain their own hosting.
