Excellent article by Andrew Potter on free speech that tells us that the real importance of free speech is not so much the freedom to speak (though that is important), but the freedom to hear what others say:

They wanted to shut us down and changing the law seemed like a genius and simple way to do it. Their logic--though they would never admit to this--was that if we don't have the information then we can't talk about it. So they made up specious reasons about safety which were ultimately shot down by the facts and actual logic.
In the end their tactics were neither genius nor simple.
