Perhaps an alternative is a "first run" mode which could do something like ask "did you intend to open vim? Y/N (answering N will close vim)". If you answer Y then you get a lesson in closing vim, if N then you always get the "first-run" mode until you answer Y?

The impact on vim users would be virtually nil whilst also respecting that non-vim users are caused problems. Who is most to blame is not usually the most helpful focus.
