We're having an ill-defined debate over when silos have to yield to public pressure and deny access to members who are deemed undesirable by a vocal group of objectors. There's no process. People have pointed out that as private companies they are free to do as they please. I'm not entirely sure that's true, especially when combined they control virtually all the speech on the net. While that might not be a violation of the First Amendment, it could easily be a violation of antitrust laws. Having run a couple of companies I know how often companies come up against those laws, even small companies, far from having a controlling stake in a large market. #
