There is no "the VIM plugin". There are multiple extensions created by VSCode users. One of them just happens to have had the temerity to re-use the logo from Bram Moolenaar's project and slap the "Vim" label on their extension.

And it's working. Despite having messier code, performance problems, and fewer Vim features implemented, it has over 3x as many users as the next most popular one listed in the VSCode extension gallery.
