An old post of mine from LRC in 2005–a good example of how copyright is–literally–censorship. (For other examples, see my Mises blog post The Patent, Copyright, Trademark, and Trade Secret Horror Files.)
So a grocery store in Canada mistakenly sells 14 copies of the new Harry Potter book a few days before its official release this Saturday, July 16. So last week a British Columbia Supreme Court judge “ordered customers not to talk about the book, copy it, sell it or even read it before it is officially released at 12:01 a.m. July 16.”
Yeah, copyright is just another type of property right.
