Re: This article conflates two important issues
"If it was 11,000 lines of the next Harry Potter, or the (11) lines of a pop song, we probably wouldn't be having this debate."
This is more like the liner notes of the next Harry Potter, or rather the textual structure necessary to get your book to fit on the pages. Or maybe the formatting rules for tagging a music file. We're not talking content. We're talking instructions. Instructions may themselves be content, but they're a special kind of content: content intended for public use. No matter how large or small it is, we're talking something that MUST be public to be useful. That falls under the Fair Use exception.
