They launched GitHub Codespaces, a free containerized dev environment with VScode & Copilot, and it's broken six ways from Sunday. VScode/Copilot extensions are constantly breaking and changing. The GitHub web interface is now much harder to use, to the point I've just stopped browsing it. Nobody over there cares if these things work. (But weirdly, the Copilot CLI works 4x better than the Copilot VSCode extension at actually writing code)
