It's worrying because it feels like MS will add more and more closed source "features" to VSCode and undermine its open source-ness. It also prevent other editors' users from building Copilot plugins. For example, there won't be a Copilot plugin for Emacs that can be accepted by Emacs's official repostiory. > Visual Studio being closed source If VScode isn't the de facto universal editor accepted by every programming language's community (notice that even this particular thread is about a VSCode plugin!), I won't be so worried.
