Pylance/Pyright are proprietary and don't even work on open source builds of VScode (theyre hardcoded to work only on MS builds of VSCode), let alone any other IDE.

From what I can tell, Pylance is proprietary and intended to "extend/extinguish" the open-source VSCode codebase with Microsoft's proprietary VSCode binaries, but Pyright is open-source.

Pyright is open source (MIT)
