This is just a glimpse at the long list of areas in which societies regulate speech, even though they're fully committed to freedom of expression. No one is really a free absolutist. For people who care about free speech, the trick is to come up with standards that would allow us to decide when speech can be regulated, and when it can't be. Absolutism is a nonstarter, because it pretends that lines won't be drawn. Information is travelling at astonishing speed.

This is a genuinely revolutionary shift, and a good one. We prize reflection and deliberation, not just accountability to the voters. In some places, the Internet is threatening to decrease deliberation. Probably the more serious risks involve an increase in social fragmentation. I mentioned that as a result of the Internet, and increased specialization, there appears to be an ever-smaller role for general interest newspapers, magazines, and broadcasters.
