You make some fair points, although I wasn't trying to be legally accurate. I agree that use isn't governed by copyright, copying is. However, to "use" code is to make a copy of it (multiple times usually). As far as attachment goes, I think the common sense meaning was clear. On GitHub, you can attach a license. I wasn't claiming that "attachment" was some feature of copyright law! On fair use, I agree with your point entirely.
