Freedom of speech does not mean doing harm to others. What might be legal in one country is not legal in another. Just by viewing pirated movies people in certain countries can be held liable. Although I am against unfair copyrights laws, there is a level of copyrights I do feel comfortable with. People can watch a pirated movie you post not knowing they might be hit with a copyright notice from their ISP or even a fine and court, what will your freedom of speech do for them then? For now all there is available to us for free is public domain material so we should treasure that and keep it out of copyrights, but in the process we should at least respect the rights of others so they in turn respect ours.
