Here’s a silly & useless attempt by CBS News to stop people from creating derivative works based on the Thornburgh Report detailing the mistakes CBS made in the Bush National Guard story. After the report was first delivered, a CBS lawyer realized that anyone with Adobe Acrobat could copy/paste the entire text and reuse it.
The only problem is that they had already published a version w/o encryption that stops copy/ paste, and it is widely available. The ubiquity of technology has changed everything. It’s time for a change in copyright law so that new works can be stimulated and CBS can turn their mea culpa report into a profit center.
