IME, these people just haven't put as much effort into it as they've put into their custom VIM/emacs configs. There might also be a sunk cost fallacy aspect to it as well

But there's nothing in VIM that I'm not able to do in VSCode. Especially when you realize you can very very easily bind VSCode commands to keys in VIM. It starts to feel like a superpower.

you can do that in the neovim vscode extension too though and everything else is faster in spades.

from my neovim config:

nnoremap <silent> zc <Cmd>call VSCodeNotify('editor.fold')<CR> nnoremap <silent> zo <Cmd>call VSCodeNotify('editor.unfold')<CR>
