When I invoke vi on a machine, I really have no idea what the implementation is. I imagine it is Vim on most Linux machines. I've been using vi for so long on so many types of systems that I only really use a safe subset anyway. I don't use any Vim extensions, so it makes sense to refer to it as vi as that is how I think of it. I imagine many others think of it the same way.
