It's not "a problem," it's a difference in philosophy. Sure, VSCode comes accessible out of the box with minimal configuration needed and a GUI-first settings interface. But that comes with its own price - your config is more restricted in what you can do and fragmented across json files, settings menus, and extension options.
In contrast, with Emacs I can change any behavior of any function and command - built-in or third-party with amazing granularity. I can change specific parts of a function without rewriting it, and I don't even need to save that - I can just write a piece of Elisp in a scratch buffer, evaluate it, and test it out immediately.
Also, you are completely wrong with your notion that Emacs is outdated. Modern Emacs tools allow you to do things in a way no other editors let you - you can control video playback, read and annotate PDFs, search through your browser history, and automate things with LLMs.
Not to mention that the problem similar to the one being discussed in the thread would never happen in the Emacs world - nobody would ever get to publish a package with obfuscated Elisp code in it. You always will have full control over the code you download to use.
