Corporations and organizations always had the ability to police their content to their own desires. A more interesting question is when does that become perhaps ethically wrong; Are people against the big companies policing content _in general_ (and thus likely against the first statement), or at people against the big companies policing content that violates popular definition of free speech once they reach a certain size?

I mean, we're discussing this topic on a site that highly polices content, albeit in one that does in different ways, but such different ways that it attracts the very commenters in this thread to read and respond to content rather than visiting other sites -- or any at all.
