Project mention: Open source versus Microsoft: The new rebellion begins | news.ycombinator.com | 2024-04-15

One of the things that comes to mind here is the fact that the default Python extension for VS Code is, perhaps surprisingly to many, not open source. https://github.com/microsoft/pylance-release
While it's possible to fork VS Code, it is not possible to fork VS Code and provide a seamless onramp towards a Python editing experience that is fully open source, because users are used to the nuances of the closed-source Pylance experience in VS Code proper. You could use the minified/compiled Pylance plugin in your fork, but you'd have no way to expand its capabilities to new hooks your fork provides. Microsoft's development process would always be able to move faster than a fork, because it could coordinate VS Code internal API development with its internal Pylance team, and could become incompatible with forks at any time.
It's worth re-reading the quote from J Allard in https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguis... with this modern example in mind.
(Also worth mentioning https://github.com/detachhead/basedpyright?tab=readme-ov-fil... which is a heroic effort to derisk this, but it's an uphill battle for sure!)
