Thanks for the share. Yeah, building upon VSCode (MIT) is a stupid idea. Regarding OpenVSX, it was developed whilst I was at Gitpod and transferred to the Eclipse Foundation. It's been many years now, so my memory might be a little dated as to what came first, but OpenVSX/Gitpod/Thiea/Eclipse origins can all be traced back to https://www.typefox.io/.

Anyway. OpenVSX is classic XKCD https://xkcd.com/2347/ territory—run by a small crew of brilliant volunteers, but the entire world depends/freeloads upon them.
