I don't disagree with any of these points. Where I disagree is that style differences make code less understandable or more difficult for others to work with to any meaningful degree. To me, it's roughly equivalent to stylistic differences in how people choose to communicate in written form. I'd genuinely be surprised if someone has more difficulty understanding code because a brace is on a line all by itself or not. I'd not be surprised to hear they have a preference or that they're annoyed to work with code that is not in their preferred style.
