If you think US courts are scary on First Amendment issues, try courts in a nation that doesn't have a First Amendment. Like the UK. And if your writing, or music, or illustrations, or photographs, ends up on the Internet… you might end up defending a defamation suit there. There's an interesting writeup on the problems at Displacement of Concepts.
Readers of this blawg know by now that I have serious antitrust concerns about the publishing, music, and film industries. Strong enforcement of antitrust is not, as some would contend, "anti-business" or economically unsound. Collusion among competitors is explicitly "anti-efficiency;" consolidation has the same effect. This is even more apparent in the music industry than elsewhere, and most particularly in classical music.
