The C/C++ extension isn't open source though, and that's where the "doesn't work on forks" DRM is implemented. At least the clangd extension is open source and is a viable alternative.

Well if it isn't open source then they should never have been using it in the first place.

But what happens when you anger the wizards? Some guy gets 4 two liter bottles of Mt Dew, and in a weekend comes up with a better plugin, and open sources it. Look it up on Monday. I just went from VSCode 1.52 to 1.99, and it's not pretty, but... Can someone convince copilot to rat out it's owners and write out a extension that runs cLisp? And all the emacs code runs in VSCode? ( I am saying this so facietously... ).
