Not entirely sure what you mean. Just in case you think so, I am not arguing for curbs on free speech. Its just another unhappy fact of life that freedom of speech by its very nature opens itself up to DDOS. The protectors of free speech have a much harder task on their hands than those who want to exploit it.

Pointing out that freedom comes at a cost doesn't necessarily mean they want freedom to be reduced. The principle is that the benefits almost always outweigh the costs.
