Once again, the approach is backwards. Instead of focusing on "harmonisation, limitations and exceptions to copyright in the digital age" the focus should be on "harmonisation, limitations and exceptions to the public domain in the digital age"
You often reprint the original "offending" content in your posts, and I assume this is partially to bait the copyright owner into going after you as well, as logically it should make sense. Do you often get a nastygram or other communication from these guys? I would assume not, as they know you are correct and that they would just be embarrassed, but I am curious!
