Emacs' TRAMP is remote-access like VSCode server - except in addition to being completely open-source, it also doesn't require that you install anything on the server, which ranges from being annoying to a show-stopper in corporate environments.

However...I love Emacs, but as much as I hate to admit it, VSCode's out-of-the-box experience is significantly better than even starter kits like Doom and Spacemacs ):

VSCode is far more "user-friendly" than Emacs or Vim at this point in time. That's definitely something that can be changed, but let's not delude ourselves...
