If you want to play the freedom game, then every voice has to be heard. Of course, we expect some limits. We don't expect, say, the New York Times or the Washington Post to give up a quarter page of advertising on their op-ed pages for free. What you end up with is a controlled market of ideas. Access for some, but not for others.
All animals are equal, but some are more equal than others.
We've heard that song before. You can't have freedom unless it is unconditional. You can't have a free market if someone is attempting to subvert it by shutting down someone else. But such tactics violate the spirit of free competition. And that's the point.
