You can easily just download the extension dist files and dump it in the extensions folder. Most extensions are open source too and VScode is not doing anything special with the extension files. They're mostly just JS. You lose out on the convenience of the marketplace but the open source version exists. If a maintainer doesn't have their extension on there, usually reaching out to them will have them upload it there too or as I mentioned, just clone the repo
