it just is man. Simple code may not have a style, but anything more complex, no, it has a style and has a lot of room for the how. Like think about it for a second, there are so many way of doing things, object oriented, functional, imperative, etc. And a programmer can mix and match those as much as they see fit. Deny it all you like, but code has a style, and is creative work. We should protect creative works.
