At this point I think it's just bunch of guys pulling pranks on each other. Most people in the industry don't care what you use as long as your code comes out clear, fast and secure.
An Emacs user bought the vim.dev domain and mistakenly forwarded to the Emacs website while trying to press some key combination using a CAPS LOCK to CTRL mapped keyboard.
I've never understood these editor wars. Isn't Vim simply a terminal editor, while Emacs is a GUI do-it-all?
Both have terminal and gui interfaces. The main difference (by default) is that vim has a mode for moving around and a mode for entering text and emacs does both at the same time (mostly by holding ctrl for moving around), but both can be configured out the wazoo to do either to some degree.
