Pitching "you might accidentally stumble upon furry porn" isn't going to win many followers. If the aim is to convince people to listen to the message, then the approach leaves something to be desired. There is a wide range between, "the most extreme thing that you could say at a child's birthday party," and, "furry porn." It would probably be better to find examples that more people can rally behind.
I disagree, because examples that many people can relate to just don't get the point across. We need some space for things that will never win many followers, because there are many different such things and we're all minorities in some aspect of our lives.
I'm not saying we need to exclude people from publishing their furry porn collection. I'm saying that using it as an example to win people over to why the Internet needs to be distributed isn't going to work well. It makes the entire idea easy to attack, "Don't want furry porn on your Internet? Sign up for Facebook Walled Garden(tm) now!"
The idea of protecting things most people don't like will always be a hard sell and it will always be easy to attack. What has to explained is the principle that we all have to accept some disgusting things in order to keep certain freedoms. You cannot make that point without mentioning something that most people find disgusting.
