But you can extend IDEs just as well as you extend your vim/emacs. Not to mention, that for some users it's more convenient to hack extensions in Python (Sublime), Javascript/Coffee (Atom) or Typescript (vscode), rather than in weird dialect of lisp (lisp is cool, I encourage everyone to go and read SICP, but not elisp) or even worse, vim script.

Elisp is a good lisp. Certainly not the best, but quite workable, and very pleasing when the environment it's in is taken into account. Emacs is open source, has better apps than Sublime,not a web page like atom and not code centric like vs code. But maybe sublime and atom could provide a similar environment as they have the tools to create parallel ones. Butnothing like org and gnus exist elsewhere, unfortunately.
