Part of the problem with the whole current copyright and patent disaster is that people are starting to think they can own anything in the abstract. For example the schoolgirl in Scotland who started blogging about her school lunches every day.
She took a picture of her lunch every day. She talked about it. The school principle made her stop. Why?
Because the principle obviously felt it was his right to do so, of course. But why?
I think it is in large part because of the current notions of copyright, in particular, this idea that you can own an idea. It's a stupid idea, but that's never stopped us before.
Obviously, all representations and thoughts about the school lunch belong to the school, and therefore they can do as they please with them, right?
