Google should strip out unreferenced symbols... but it probably doesn't matter

> Some people in CompSci tends to think in overly strict principal lines, wanting the grey to go away. Perhaps this has something to do with how a computer works, in binary. But it's not how law works.

Or perhaps it's how reasonable people think? Many laws are designed to be wishy washy so that the people who speak in vague illogical terms and who spend money on lawyers can take advantage of those reasonable people who don't. Copyright is just one of the many examples of this. Patents are an obvious other.

The fact that this discussion is currently over 100 comments of bickering over the understanding of copyright, likely by professionals who actually operate in the copyright field daily, should tell you that the concept of copyright is beyond grey, and very vague. This is not a subject matter that any law could ever be fair about. It is not a subject matter that you could expect juries to reasonably agree upon in a consistent matter. It is simply a bad use (not just a bad implementation) of law.
