@cnk so. That is a long story. They want to be legal under the term of 'fair use'. And want to protect history of books, software, web and alike. They lost lawsuits over ebooks. It's a big problem I think. Sure copyright is to protect the writer or producer. But at the same time we can't just lose all the data from the past if we aren't allowed to archive it?!?
I'm no expert in the law, but I hope we can archive old software and digitalize other content in a legal manner.
